The Spanish Journal of Gastroenterology (Revista Española de Enfermedades Digestivas), the official Spanish Society of Digestive Diseases (Sociedad Española de Patología Digestiva) (SEPD), Spanish Society of Gastrointestinal Endoscopy (Sociedad Española de Endoscopia Digestiva) (SEED) and Spanish Association of Digestive Ultrasonography (Asociación Española de Ecografía Digestiva) (AEED), publishes original papers, editorials, reviews, case reports, letters to the Editor, images in digestive diseases, and other special articles on all aspects referring to the digestive diseases. Manuscripts must be written following recommendations issued by the International Committee of Medical Journal Editors (Available at: http://www.icmje.org) , and according to the following guidelines: the journal has two versions: a) print and b) online. The print version is available in English or Spanish. The online version includes articles in English and Spanish. This version publishes Letters to the editor in English or Spanish. Once a manuscript has been accepted, its author(s) should submit an English version within a month’s term after acceptance date for the online publication. Manuscripts in English will be reviewed by experts. Should the authors wish, the Journal may provide contact information for companies specialized in the translation of biomedical texts. Authors may be asked to contact professionals regarding the correction of the English content of manuscripts either before or after acceptance. This expense will be the responsibility of the authors. Should the translated paper fail to be received at the Journal’s editorial office within this timeframe, paper acceptance will be cancelled and the paper will not be published.

Types of authors

1. Corresponding author. The person responsible for submitting a paper to the Journal

and then receiving/sending different versions as required by the editorial

process. This is the author the Editorial Committee will be in touch with for any

manuscript-related issues, and needs not be the manuscript’s fi rst author.

2. First and second author as co-authors. Under selected, adequately justifi ed circumstances

in the initial letter to the Editor-in-Chief, a corresponding author may

propose another author to appear as fi rst author in co-authorship with the second

author, such that both authors would share the fi rst position in the publication

(shared authorship).

3. Contributor. As in the section above, a list of contributors may be submitted to

the Editor-in-Chief. If approved, the list will be included in an “Acknowledgments”

section at the bottom of the manuscript. Five is the maximum number of acknowledged

contributors.

4. Authorship by scientifi c societies (or offi cial groups thereof). They may be included

in the authors list in full-name format, with the corresponding abbreviation

at the bottom of the authors section.

Example: Sociedad Española de Patología Digestiva, author, author.

SEPD: Sociedad Española de Patología Digestiva.

A list of the scientifi c society’s members who contributed to the article (maximum,

20 authors) may be appended at the bottom of the manuscript; the number of contributors

may be extended after consultation with the Editor-in-Chief if the list is included

in an appendix.

Should an author be included in representation of a scientifi c society, an asterisk

will be used next to his/her name in the authors list to identify him/her, which will then

be explained at the bottom of the authors section.

Example: author, author (*), author.

(*) on behalf of the SEPD (Sociedad Española de Patología Digestiva).

Submission

All types of manuscripts must be submitted through the website www.reed.es by

the corresponding author (the author who runs the paper through the online tool and

who will receive all communications along the validation process through to publication

and thereafter in case of reply letters or editorial issues). It is necessary that the full

article and then a version with no identifi ed authors or sites be separately submitted to

ensure a blind review (there are blancks available for it in the online editorial process).

Please check no such identifi cations are present in the heading or body text. The editors

and publishers are not responsible for the opinions expressed by contributors to the

Journal. Accepted manuscripts become the permanent property of The Spanish Journal

of Gastroenterology (Revista Española de Enfermedades Digestivas) (Spanish Society

of Digestive Diseases “Sociedad Española de Patología Digestiva”). Shared authorship

may be approved for selected papers if adequately warranted by the corresponding

author in a letter to the Editor-in-Chief, as discussed above, stating that both authors

equally contributed to the manuscript.

The “Revista Española de Enfermedades Digestivas” is an open-access journal,

which means that all its contents are accessible free of charge to non-commercial, individual

users. Individual users are permitted to read, download, copy, distribute, print,

search, or reference full article texts in this journal without prior permission from the

publisher or the author, according to the defi nition of “open access” by BOAI (Budapest

Open Access Initiative). Works may be reused provided their integrity remains unchanged,

and their authors are properly referenced or quoted; the rights to derivative works

are held by the original copyright holders.

A regular monographic issue of Revista Española de Enfermedades Digestivas may

be scheduled with the standard layout but including only manuscripts on the selected

topic. Authors interested in including their manuscript in an already scheduled monographic

issue should discuss it in the initial letter submitted by the corresponding

author to the Editor-in-Chief.

Form and preparation of manuscripts

Cover letter. All submissions to REED must be accompanied by a cover letter addressed

to the Editor-in-Chief. The authors must briefl y explain the type of the article

they are submitting, what new insight the study provides and the contribution of all the

authors following ICMJE norms.

It should be explicitly stated that the article is not currently under review by any

other journal and that it has not been published previously. The authors must declare any

confl icts of interest (again following ICMJE norms (available at www.ICMJE.org)) and if

the article has received any kind of fi nancial support. If during the editorial process changes

to the original article are requested, when the new version of the manuscript is sent,

a new cover letter that is different from the original (a copy of the original letter will not

be accepted) must be included which lists in an orderly fashion the changes made and

any issues the authors wish to take up with the Editor-in-Chief (see the Editorial section).

TYPES OF MANUSCRIPTS

1. ORIGINAL PAPERS

Manuscripts describing original research must be written in English or Spanish,

they must be concise, well organized, clearly written, and should not exceed 3,000

words (including the abstract, text, tables and figures), and 35 references. The illustrations

must be 3 tables and 3 figures at most. The title must not exceed 130 characters

(excluding spaces), and the abstract must not exceed 250 words. Acceptance of original

manuscripts will be based upon originality and importance of the investigation. These

manuscripts will be assessed by the editors and will be peer-reviewed in a majority of

cases by two experts from the Editorial Committee, including the section’s Associate

Editor. Authors shall be responsible for the quality of language and style and are strongly

against submitting manuscripts which are not written in idiomatic English and Spanish

or English. In case of articles submitted in Spanish, authors should submit an English

version within one month after acceptance. The Editorial reserves the right to reject

poorly written manuscripts even if their scientific content is qualitatively suitable for

publication. Manuscripts are submitted with the understanding that they are original

contributions and do not contain data that has been published elsewhere or are under

consideration by another journal. Meeting abstracts do not constitute prior publications.

Randomized clinical trials should follow the CONSORT guidelines (www.consort-statement.

org; and should be registered as clinical trials (www.clinicaltrial.gov o WHO´s

International Clinical Trial Registry Platform). For cohort and case-control studies and

cross-sectional studies the STROBE norms should be followed (www.strobe-statement.

org). For studies analyzing diagnostic accuracy, the STARD norms are recommended

(www.stard-statement.org)

Sections should be included in the following order: title page, abstract, introduction,

material and methods (or patients and methods), results, discussion, references,

acknowledgment of any intervening grant or financial support, references, tables, figure

legends, and figures. All pages must be numbered in the upper right corner, starting

with the title page.

All original articles must fulfill appropriate recommendations according to the type

of study to which they refer and are specified in the official website of the REED (online

version of the publication norms).

Submission of any checklist tables corresponding to the relevant article is mandatory.

Title page or cover page

This section must include: full title, running title (less than 50 characters) for headings,

author name(s), key words, list of abbreviations, and disclosures.

Title. The title should not exceed 130 characters, not including spaces between

words, and must reflect the manuscript’s main subject. It should all the information

necessary to make electronic recovery of the article as sensitive and specific as possible.

The use of acronyms and abbreviations should be avoided. The species used for

work with experimental animals must be indicated in the title. Inclusion of sentences

such as “A propos of a case” or “Literature review” o “Experience in our institution”

is not encouraged.

Author names. This page must contain: the full name of all authors; the names of

department(s) and institution(s) where the work was done; and in a multi-authored work

involving more than a single institution, indicate individual affiliation by means of a

superscript Arabic number. It is necessary the e-mail address of all authors that will be

used for the verification of the right cession of the journal, too. Where appropriate, the

16 digit ORCID code should also be included.

Contact information. Please include full name, telephone number, e-mail address,

and address of the author to whom correspondence, galley proofs and offprint requests

will be sent.

Key words. A list of keywords should be included in the same page. Key words (three

to eight in total) complement the title and help in paper identification. Terms obtained

from the Index Medicus medical subject headings (MeSH).

List of abbreviations in the order of their mention in the paper. Do not abbreviate

otherwise unless a term is used more than five times in the manuscript. The full term

substituted for by an abbreviation must precede the latter, except for standard measuring

units. Units should be preferentially expressed as International System units.

Abbreviate units of measure only when used with number. Chemical, physical, biologic

and clinical units must be always strictly defined. Abbreviations used in figures or tables

should be defined in the legend.

Disclosures. All authors must disclose any potential conflicts (financial, professional,

or personal) that are relevant to the manuscript. If the authors have nothing to disclose,

this must be stated. We recommend the ICMJE model (www.icmje.org/coi_disclosure.

pdf) be used.

Abstract

The abstract must be written as continuous text organized as background and

study’s purpose, methods, main results, and conclusions. Only conclusions directly

supported by data should be included. Do not use abbreviations, footnotes or references

in the abstract. The abstract may not exceed 250 words.

Back to index

Introduction

Provide the minimum background information that will orient the general reader.

The aims and an a priori hypothesis must be stated.

Back to index

Methods

These will be described in detail for assessment and repetition by other researchers.

For methods that are used without significant modification, citation of the original work

will suffice. Ethical standards met by researchers for both animal and human studies

must be briefly described. Studies in humans must have express authorization by the

local ethics committee for clinical trials, which must be clearly stated in the manuscript.

That means that informed consent was obtained from each patient included in the study

and that the study protocol conforms to the ethical guidelines of the 1975 Declaration of

Helsinki (1983 Revision). Any paper that is a randomised controlled trial should adhere

to the guidelines that can be found at the following web-site: www.consort-statement.

org. Refer to individual patients by number, not by initials. Particularly in figures, names,

initials and hospital numbers must not be included. When experiments carried

out in animals are described, provide assurance that all animals received humane care

according to guidelines issued by an international research council or institution, or

a national law on laboratory animal care and use. Include the names and locations

(city and state or country) of manufacturer when mentioning drugs, tools, instruments,

prostheses, designs software, etc. Statistical methods used must be described. Studies

must include experiments and/or control groups; otherwise, actions implemented for

bias avoidance must be explained, as well as their potential effect on study conclusions.

Statistical terms, abbreviations and most symbols should be defined. The software used

should be stated.

Back to index

Results

These must be concise and clear, with a minimum necessary number of tables and

figures. Mention all tables and figures. Findings should be presented with the appropriate

indicators of mean error or uncertainty (for example, confidence intervals) When

numerical results are given, derived forms (percentages) should not be given but also

the absolute values on which the calculations were made.

Unnecessary data duplication or repetitions should be avoided both in the text and

the figures and tables.

Back to index

Discussion

Except in review articles, a thorough inclusion of literature references is not necessary.

Own findings shall be related to those of previous investigations, and differences

between results obtained and those seen by other authors will be noted. The discussion

should not include new results. Implications of the findings should be discussed, including

possible explanations and implications for clinicians, minimizing reiteration of the

results, avoiding repetition of material in the introduction, and keeping a close focus on

the specific topic of the paper. Care should be taken not to overstate the importance of

findings or to draw conclusions which are not fully justified by the data.

Likewise, the authors should comment the strengths and weaknesses of the study

and the unanswered questions and future research.

Back to index

Acknowledgment

Acknowledgment of any personal assistance and intervening grant or financial support,

either public or private.

Back to index

References

Bibliography references will be identified in the text by Arabic numbers between parentheses.

Only literature that is published or in press (with the name of the publication

known) may be numbered and listed; abstracts and letters to the editor may be cited. List

all authors up to three, using three and “et al.” when the number is greater than three.

References will be consecutively numbered following the order in which they are quoted

in the text. Personal communications and unpublished data should not be in included

(they may be quoted between parentheses in the text). Journal name abbreviations must

be those included in the National Library of Medicine’s Index Medicus. Style and punctuation

TABLES

Double-spaced and each typed on separate sheets, tables should be identified by

Arabic numbers and a title in their upper margin, and must include explanatory notes

below the table. Do not duplicate material presented in a figure.

Authors should place explanations in the table footer, not in the title. The footer should

also include explanations of all abbreviations not in common use. For table footers, the

following symbols should be used in this order: * † ‡ § || ¶ ** †† ‡‡. §§, ||||, ¶¶, etc.

Back to index

FIGURE LEGENDS

Number with Arabic numerals in the order mentioned in the text. Provide a title (this

should not appear on the figure itself). Legends should include enough information needed

for accurate interpretation, thus rendering text interrogation unnecessary. Explain

all abbreviations and symbols. For any copyrighted material, indicate that permission

has been obtained (send a fax of this permission). Photographs of identifiable persons

must be accompanied by a signed release that indicates informed consent. If your

figures include text, an 8 to 10 point font should be used.

Back to index

FIGURES

Photographs must be submitted in a modifiable format (jpg, ppt or tiff) and with a

resolution of 300 pixels per inch in a separate archive rather than embedded in the text.

It is necessary that the minimum size was 10 cm wide. Figures must not repeat data

already included in the text. Object photographs and microphotographs should include

a ruler allowing measure calibration. Symbols and arrows included to guide interpretation

must contrast with the background. Patient name and other patient-identifying

data should not be included. Black and white microphotographs are better than color

microphotographs for reproduction. Color illustrations will be included only when they

represent an outstanding contribution to paper comprehension. As a general rule, the

total number of tables and figures should be not higher than six.

Back to index

2. RAPID COMMUNICATIONS

These are original studies which report novel findings, unreported or underreported

new techniques, small series of unusual findings or preliminary results from a research

project, study, etc. They should contain no more than 1,200 words, 15 references, an abstract

of 100 words and up to 4 figures or tables. These manuscripts will be reviewed within

15 days by the section’s Associate Editor, and by the Editor-in-Chief or Executive Editor,

and any changes suggested should be implemented by the authors within one week.

Back to index

3. EDITORIALS

This section consists of comments on articles published in the Spanish Journal of

Gastroenterology and are invited by the Editor or Associate Editors. They should be

no longer than 1,500 words excluding references, 3 authors at most (exceptionally 4 if

adequately justified to the Editor-in-Chief), no more than 25 references, and a table or

figure can also be included. Please provide a title page. The paper will be reviewed by

the section’s Associate Editor, and/or the Editor-in-Chief or Executive Editor.

Back to index

4. REVIEWS

Narrative Reviews. Review articles on selected clinical and basic topics of interest for

the readers of the Spanish Journal of Gastroenterology will be solicited by the Editors.

Authors interested (5 at most) in contributing reviews are requested to first contact the

Executive Editor or one of the Associate Editors with an abstract of the proposed article,

arguing its usefulness. Review articles are expected to be clear, concise and updated.

Review articles must be accompanied by a summary. The word limit for review articles

is 3,500 words excluding the summary, references, tables and figures. The inclusion of

tables and figures to summarize critical points is highly desirable, with 5 figures and/or

tables and 50 references at most. Review articles are reviewed by the Editorial Committee

and may be sent to outside expert reviewers before a final decision for publication

is made. Revisions may be required. Please provide a title page. Papers will be reviewed

by the section’s Associate Editor and by the Editor-in-Chief or Executive Editor. Please

find this under “Reviews” within the online tool.

Systematic reviews and Meta-analyses. The Revista Española de Enfermedades

Digestivas encourages the publication of systematic reviews and meta-analyses. Manuscripts

will initially undergo a methodological review by the section’s Associate Editor

(SRMA), and then a peer review similar to that for original papers. They will be of the

same length, with the same number of tables and figures, as narrative reviews, with

a maximum of 100 references. In both cases the PRISMA norms should be followed

(www.prisma-statement.org). Please find this under “Reviews” within the online tool.

Rapid reviews. These are shortened syntheses of knowledge in which the usual requirements

for a systematic review are simplified with the aim of accelerating the diffusion

of information. Such studies will deal with innovative techniques, health care decision

making, technological assessment, etc., which require a simplified and rapid analysis.

They will contain a maximum of 2,500 words and up to 25 references. Four figures or

tables will be allowed. It is recommended that the number of authors should not exceed

four. Authors interested in submitting a rapid review must contact the Editor-in-Chief or

an Associate Editor. Papers will be reviewed within 15 days by the section’s Associate

Editor, and by the Editor-in-Chief or Executive Editor; suggested changes should be made

by the authors within one week. Please find this under “Reviews” within the online tool.

Authors interested in contributing rapid reviews are requested to first contact the

Editor or Associate Editors.

5. IMAGES IN DIGESTIVE DISEASES

The images in digestive diseases section is designed to highlight interesting pathological,

radiographic, endoscopic, or ultrasonographic findings along with their clinical

correlation and relevance. Submissions should be limited to no more than 200 words and

include high-quality gross photos and/or histomicrograph(s) or imaging studies (minimum

resolution: 300 dpi). Format must be .jpg or .tiff or similar. Capture from the original source

is recommended. These should include a brief clinical history, detailed description of the

image(s), the differential diagnosis, and 3 references, 3 figures, and 4 authors at most.

Papers will be reviewed by the Editor-in-Chief or Executive Editor, and when needed by

the section’s Associate Editor; when published, brief comments by the Editors and, when

appropriate, by a reviewer will be included at the bottom of the manuscript.

Back to index

6. RESEARCH LETTERS

The Editorial Committee reserves the right to edit letters received. This type of scientific

letters may refer to an article previously reported in the Journal (within the past

two years) and, when entailing a reply, the latter’s authors will be given the opportunity

to answer back; whenever possible, both papers will be reported in the same regular

issue. In this case, the letter will be a letter to the editor, identified as such in its

heading (Dear Editor). Research letters may also include observations, well documented

uncommon cases, or brief scientific opinion articles on an interesting subject. In

both cases, the structure will be devoid of sections such as introduction, material and

methods, results, discussion, conclusions, etc. – this should be a free-text manuscript

without sections. They may be subjected to peer review and undergo editing for clarity

and brevity. Letters must not be longer than 300 words, and may contain 1 table

or figure, only when essential for understanding the text, a total of 5 references, and

3 authors at most. Letters must have a title. A title page should be provided. A maximum

of 4 authors will be allowed. The paper will be reviewed by the Editor-in-Chief or

Executive Editor, and when appropriate by the section’s Associate Editor or reviewer.

Back to index

7. CLINICAL PRACTICE GUIDELINES

These are a set of systematically developed recommendations to facilitate physician

decision making with the aim of optimizing patient care; to this end the most appropriate

diagnostic and/or therapeutic options are selected for a given health issue or specific clinical

condition. These should be based on the GRADE (http://www.gradeworkinggroup.org/)

system, with the coordinator(s) (maximum 2) providing the required tasks, time schedule

and work plan, as well as a systematic literature review and recommendations development.

These aspects will be communicated by the corresponding author to the Editor-in-Chief in

his/her initial letter. Guidelines may be supported or promoted by scientific societies. The

maximum number of authors is 35, with every author representing a scientific society or

group thereof identified as such. Maximum article length is 3,500 words, with a maximum

of 150 references. Papers may include 3 figures and 3 tables (or a maximum of 6, exceptionally

7, both included), one of which must be a flow chart adequately laying out the involved

methodology. A title page with keyboards should be provided. Manuscripts will be reviewed

by an external panel of experts in the field, who cannot be members or any of the scientific

societies promoting the set of guidelines. They will also undergo a methodological review by

the section’s Associate Editor (SRMA). Please fin this under “Reviews” within the online tool.

Back to index

8. SPECIAL ARTICLES

Special articles are on a variety of topics and may include practice guidelines, in-depth

scientific reviews, meeting reports, consensus documents, points of view and commentaries

on social policy. The maximum number of authors will be 8 and where necessary

more authors may be reported as a supplement at the end of the article. The length of

each article is should not exceed 3,000 words and 35 references. However, exceptionally,

when duly justified to the Editor-in-Chief, up to 15 authors may be included, provided it

is deemed essential by the Editorial Committee. Maximum length is 3,500 words, with

a maximum of 100 references. A title page including keywords is to be provided. Papers

will be reviewed by the Editor-in-Chief or Executive Director, and when appropriate by

the section’s Associate Editor. Please fin this under “Reviews” within the online tool.

Back to index

9. OBITUARIES

These apply to individuals who are outstanding either due to their professional development

or the advances they have made in the field of digestive disorders. Such texts

will be written on invitation by the Chief Editor or proposed by readers to the Chief Editor.

They may be up to 800 words long, and be accompanied by a photograph (in the

latter case a maximum of only 600 words is allowed). They will not include references

and will not be referenced in PubMed. They may be signed by one or two authors.

Back to index

ETHIC RESPONSIBILITIES AND AUTHORSHIP

No studies which have been previously published will be accepted. In those studies

in which some type of plagiarism, duplication or redundancy is identified, the

manuscripts will be referred to the Ethics Committee of the Journal and the guidelines

established by the Committee on Publication Ethics (COPE; http:// publicationethics.org/

resources/flowcharts) will be followed. Authors are held responsible for obtaining permission

for the partial reproduction of materials (text, tables, figures) included in other

publications, and for accurately quoting their origin. Authorization must be requested

from both the author(s) and publishers of said material.

Conflict of interest: The Spanish Journal of Gastroenterology (Revista Española de

Enfermedades Digestivas) expects authors to declare any commercial involvements that

may represent a conflict of interest in connection with their articles. Within the authors

list only individuals having intellectually contributed to the submitted work should be

included. Helping in data collection and taking part in a technique are not sufficient

criteria for inclusion as author. Overall, to be included in an author’s list the following

requirements should be met:

1. Having taken part in the conception and implementation of the work that gave

rise to the paper.

2. Having taken part in the writing of the text and its potential revisions.

3. Having authorized the final version for publication. Statements and opinions

expressed in the articles and communications in The Spanish Journal of Gastroenterology

(Revista Española de Enfermedades Digestivas) are those of the

author(s) and not necessarily those of the Editorial Committee or publisher, and

the Editor(s) and publisher rejects any responsibility or liability regarding any

authorship conflicts arising in published papers.

Neither the Editorial Committee nor the publisher guarantees, warrants, or endorses

any product or service advertised in the Journal, nor do they guarantee any claim made

by the manufacturer of such product or service.

Authors must declare if there is any financial or personal relationship which might

affect the objectivity of the results. This statement must be included in all original articles,

editorials, review and special articles.

Authors belonging to a research team. When a study is signed by a large research

group (e.g with more than 20 members) the corresponding author must be identified in

representation of the whole group. If the number of signing authors is greater than 12,

the first six will be identified in order and the remaining authors will be cited together

with their affiliation in the Acknowledgements at the end of the article.

In this way, all the authors are identified in PubMed following the order in which they

appear in the Acknowledgements and the group is registered in PubMed.

When a study is signed conjointly by a working group, a panel of experts or a

committee, etc., the name of the working group will appear in the heading and the list

of authors and their affiliations will be given in the Acknowledgements at the end of

the manuscript. This way PubMed will register all the authors in the working group.

Definition of the responsibilities shared by authors. When the signing authors of a

manuscript consider that two authors should figure as first or senior authors, this should

be explicitly stated in the Acknowledgements. For example, “Dr A and Dr B contributed

equally as co-first authors”.

EDITORIAL PROCESS

Once successful submission of a manuscript has taken place, an acknowledgement

will be sent by e-mail to the corresponding author. The number of the manuscript should

be used by the authors in all communications with the Editorial Department. Authors

should be aware that all manuscripts which fully comply with the submission requirements

outlined will be evaluated by the Editorial Committee of The Spanish Journal of

Gastroenterology (Revista Española de Enfermedades Digestivas), and two experts from

the National Editorial Committee. The Editor can choose to early reject a manuscript without

peer review if the manuscript is incomplete or unlikely to be accepted. Evaluation

will be according to a protocol established for this purpose, and will remain anonymous;

author names and paper origin, therefore, must not be included in any of the manuscript

sections. After review, the corresponding author will be notified of the decision to

accept or reject the manuscript for publication. This letter will be accompanied in most,

but not all, cases by the comments of the reviewers. This letter will be sent via e-mail.

In some cases, authors will be invited to submit a revised version of the manuscript

for further review. This invitation does not imply, in any case, that the revised version will

be accepted for publication. In general, revised manuscripts must be received within one

month of the date of the first decision, otherwise they will be considered as “de novo” manuscripts.

No paper will be definitely accepted until all corrections have been completed. To

facilitate work by the Editorial Committee, authors must underline all changes made in the

revised version of the manuscript. A cover letter must state that the revised manuscript has

been revised according to the comments made by the Editor and the reviewers and must

contain a point by point response to the reviewers. The Spanish Journal of Gastroenterology

(Revista Española de Enfermedades Digestivas) reserves the right to introduce changes and

modifications in the study, without altering its contents, in order to improve understanding.

Papers will be published in groups according to scientific criteria and editorial availability.

FAST TRACK REVIEW

Fast track review is available at REED but only for original articles or reviews that

provide findings of great impact in the clinical or basic science fields. They would be

included as a Rapid Communication or Rapid Review, as described above.

Authors may request a fast track review from the Editor-in-Chief by sending a cover

letter justifying the need for this type of review. The Editor-in-Chief will inform the authors

as to the suitability of their article for this type of review within a period of 4 days.

If the request is granted, a first editorial decision will be taken within 14 days and if the

article is accepted, priority will be given to on-line publication and keeping all the steps

of the editorial process.

Confirmation of the fast track process does not guarantee acceptance of the manuscript.

If the manuscript is not accepted for fast track review, it could be assessed

following standard procedures.

PROOFS

Proofs will be sent to the corresponding author to be checked. Please pay particular

attention to general layout and quality and accuracy of figures and tables in the proofs.

Further changes or additions to the edited manuscript after these corrections cannot be

accepted. Proofs must be returned within 48 hours of receipt, by e-mail (www.reed.es)

if the corrections are minor, to expedite publication.
