Transcript

  • 1. Content Clinical Gastroenterology and Hepatology publishes original papers, review articles, case reports, and special category articles on all aspects of the digestive tract and the liver. Manuscripts must be prepared in accordance with the "Uniform Requirements for Manuscripts Submitted to Biomedical Journals" developed by the International Committee of Medical Journal Editors (N Engl J Med 1991;324:424-428). Ethics Clinical Gastroenterology and Hepatology strongly discourages the submission of more than one article dealing with related aspects of the same study. In almost all cases, a single study is best reported in a single paper. The journal editors consider research/publication misconduct to be a serious breach of ethics and will take action as necessary to address such misconduct, which includes submission or publication of information that: • Is intentionally erroneous, • Has been published elsewhere by a different author without acknowledgment (plagiarism), • Has been published elsewhere by the same author without acknowledgment (duplicate publication), or • Is subsequently published elsewhere by the same author without acknowledgment, attribution, or permission from the AGA Institute, as holder of the copyright, to reprint or adapt the material. Breaches in these standards may result in proscribed submission for all authors of the concerned manuscript and, when appropriate, notification of the authors' institutions. All authors are fully responsible for the content of the manuscript. The publication of abstracts is not considered duplicate publication but should be disclosed in the cover letter accompanying the manuscript submission. Authorship Each author must have participated sufficiently in the work to take public responsibility for the content of the paper and must approve of the final version of the manuscript. Authorship should be based on substantive contributions to each of the following: • Conception and design of the study; • Generation, collection, assembly, analysis and/or interpretation of data; • Drafting or revision of the manuscript;
  • 2. • Approval of the final version of the manuscript. Conflict of interest Authors (original articles and review articles) Authors of original research articles and review articles should disclose at the time of submission any financial arrangement (e.g., consultancies, stock ownership, equity interests, patent-licensing arrangements, research support, major honoraria, etc.) they may have with a company whose product figures prominently in the submitted manuscript or with a company making a competing product (see Copyright Assignment, Authorship Responsibility, Financial Disclosure, and Institutional Review Board/Animal Care Committee Approval form). Interactions that occur within 2 years before the submission date of an article are pertinent. The conflict of interest form can be found on www.cghjournal.org. Such information will be held in confidence while the paper is under review and will not influence the editorial decision; but if the article is accepted for publication, the editors will usually discuss with the authors the manner in which such information is to be communicated to the reader. All funding sources supporting the work and all institutional or corporate affiliations must be acknowledged in a footnote. Reviewers Reviewers of research articles will be disqualified from reviewing if they: • Have had an ongoing collaboration, original publications, or grants with the authors within the previous 2 years, except in the case of being a part of a multicenter group from a different site; or • re from the same institution as the authors. Reviewers should disclose at the time of submission any financial arrangement (e.g., consultancies, stock ownership, equity interests, patent-licensing arrangements, research support, major honoraria, etc.) they may have with a company whose product figures prominently in the submitted manuscript or with a company making a competing product. Interactions that occur within 2 years before the submission date of an article are pertinent. Editorialists Editorialists will be disqualified from writing an editorial if they: • Have had an ongoing collaboration, original publications, or grants with the authors within the previous 2 years, except in the case of being a part of a multicenter group from a different site; or • Are from the same institution as the authors.
  • 3. Editorialists should disclose at the time of submission any financial arrangement (e.g., consultancies, stock ownership, equity interests, patent-licensing arrangements, research support, major honoraria, etc.) they may have with a company whose product figures prominently in the submitted manuscript or with a company making a competing product. Interactions that occur within 2 years before the submission date of an article are pertinent. If the editorial is accepted for publication, the editors will usually discuss with the authors the manner in which such information is to be communicated to the reader. Cover letter Clinical Gastroenterology and Hepatology strongly encourages authors to suggest 3 to 4 referees (include the mailing address, electronic address, phone, and fax numbers) and the Associate Editor they believe best qualified to review their paper. Authors may also list a non-preferred Associate Editor and non-preferred referees, but the ultimate selection of an Associate Editor and referees is at the sole discretion of the Editor and Associate Editor, respectively. State reasons for deviations, if any, from standard format and clarify any potential conflict related to the exclusive nature of the publication. The cover letter must also categorize the manuscript into one of the four following groups: Clinical Alimentary Tract, Clinical Liver/Pancreas/Biliary, Basic Alimentary Tract, or Basic Liver/Pancreas/Biliary. Manuscript preparation Electronic submission All manuscripts submitted to Clinical Gastroenterology and Hepatology are made available for online review. Authors may submit their manuscripts, with figures and tables, electronically via our website, http://www.editorialmanager.com/cgh . Please note that electronic submission will decrease review time by as much as 2 weeks, so authors are encouraged to use this method when possible. Complete instructions for online submission are located on the Website. Note: If you have submitted your manuscript electronically, you do not need to submit a hard copy. If your manuscript is accepted you will be asked to provide the editorial office with hard copies of the missing materials. Before entering the Website, authors are asked to have their manuscript saved in Rich Text Format (.rtf) and each figure saved as a separate electronic file, preferably named as "figure 1.tif," "figure 2.jpg," etc. Image File Formats: We support the following among dozens of file formats: .bmp, .gif, .jpg, .pbm, .pcx, .png, .tif, .eps, and .xbm, along with TARGA and Photoshop files. (ChemDraw, Excel, PowerPoint, SigmaPlot, and Equation Editor formats are not supported at the time.) Your file formats can be mixed. Tables: Tables should be prepared without the use of tabs; most table editor programs can be uploaded successfully. The word count for electronic submissions is approximately 5,000-6,000 words.
  • 4. Manual submission Since all manuscripts are made available for online review, if you are unable to submit your manuscript electronically, the Editorial office can do so on your behalf. However, effective January 2004, authors will incur a $75 charge for the processing and uploading of manual and email submissions. All manual and e-mail submissions must be accompanied by a check, a purchase order, or credit card information or the submission will not be processed. Note: If you have submitted your manuscript electronically, you do not need to submit a hard copy. If your manuscript is accepted you will be asked to provide the editorial office with hard copies of the missing materials. Submit 1 complete manuscript typed in 12-pt font and double-spaced with 1-inch margins. Limit of 21 pages (approximately 4,000 words for original articles and 5,000 - 6,000 words for review articles) including tables, figures, and references (2 figures = 1 typed page). One diskette containing the text of the manuscript--saved in Rich Text Format (.rtf)--must accompany every manuscript and revision. Also, please include an electronic copy of your cover letter, and in the case of a revision your point-by-point reply to reviewers, on the diskette. Arrange manuscript as follows, each component beginning on a separate page: (1) title page, (2) abstract, (3) introduction, (4) materials and methods, (5) results, (6) discussion, (7) references, (8) figure legends, (9) tables. Place page number and first author's last name at top of each page. Cite references, tables, and figures consecutively as they appear in the text. Authors are responsible for applying for permission for both print and electronic rights for all borrowed materials and are responsible for paying any fees related to the applications of these permissions. Title page Title--Use no abbreviations. Limit: 120 characters with spaces. Short Title--Limit: 45 characters with spaces.

  • 5. Reporting clinical trials Randomized controlled trials should be presented according to the CONSORT guidelines (JAMA 2001;285:1987-1991 or http://www.consort-statement.org ). At manuscript submission, authors must provide the CONSORT checklist with a diagram that illustrates the progress of patients through the trial, including recruitment, enrollment, randomization, withdrawal, and completion, and a detailed description of the randomization procedure. The CONSORT checklist can be found on www.editorialmanager.com/cgh under Instructions to Authors. Manuscripts that fail to comply with CONSORT guidelines will not be reviewed for publication. Abstract Limit: 250 words. Do not use abbreviations, footnotes, or references. Authors should submit a structured abstract of no more than 250 words organized into the following categories as applicable: Background & Aims: Describe the importance of the study and the precise research objective(s) or study question(s). Methods: Methods should include information on the following aspects of study design when applicable. The methods section may employ subheadings at the discretion of the author. • Design--describe the basic study design, e.g., randomized controlled trial, cross sectional study, cohort study, case series, survey, etc. • Setting--specify whether the study was conducted in a primary or tertiary care setting, in an ambulatory care clinic or hospital, in the general community, etc. • Participants--indicate the number of study subjects and how they were selected, recruited, and assigned to the intervention. • Intervention--report the method of administration and duration of the intervention. Results: Provide the main outcomes of the study, including confidence intervals or P values.
