Guide for Authors

  • GASTROINTESTINAL ENDOSCOPY publishes original papers reporting investigations and observations relating to endoscopic procedures used in the study and treatment of digestive diseases. All submissions undergo peer review.Submissions may be accompanied by supplemental materials posted to the electronic version of the journal; such materials also will be subject to peer review. Careful adherence to submission guidelines will avoid unnecessary delays, asincomplete submissions may be returned to the authors before initiation of the peer review process.

    ETHICAL CONCERNS

    • Prospective authors should refer to the UniformRequirements for Manuscripts Submitted to BiomedicalJournals1 (http://www.icmje.org ) to familiarize themselveswith ethical conventions of publication; specifically,the issues of redundant or duplicate publication, authorshipcriteria, and potential conflicts of interest.
    • The Editor reserves the right to investigate alleged improprietiesrelated to these conventions.
    • When questions of scientific misconduct or dishonesty inresearch occur, the Editor reserves the right to proceedaccording to the guidelines of the Office of ResearchIntegrity.2 Authors may be asked to provide the appropriatedocumentation of compliance, as well as the data onwhich the manuscript is based.
    • Investigations involving human subjects or animals musthave prior approval of the appropriate institutional reviewboard or an equivalent body. If your research involves interacting with living human subjects or with the data from living human subjects and if you intend to make the results of your research public (eg, publish an article in GIE), your research meets the definition of human subjects research and requires IRB review. This includes retrospective chart reviews.3,4
    • In countries where institutional review is not establishedpractice, a statement must be included in the methodssection that the research was carried out in accordancewith the Helsinki Declaration.3

    REGISTRATION OF HUMAN CLINICAL TRIALS
    Gastrointestinal Endoscopy follows the International Committee of Medical Journal Editors (ICMJE)'s Uniform Requirements for Manuscripts Submitted to Biomedical Journals. All prospective randomized clinical trials submitted to GIE must have been registered BEFORE the trial begins through one of the registries approved by the ICMJE, and proof of that registration, including the date registered and the registration number, must be submitted to GIE along with the article. IRB approval information must be included in the manuscript text, including the date of IRB registration. As of January 2015, all prospective human trials (not just randomized clinical trials) must also have been registered before the trial began (not just randomized clinical trials). For further details and a list of ICMJE-acceptable registries, please go to http://www.icmje.org.

    SPECIAL SUBJECT REPOSITORIES

    Certain repositories such as PubMed Central ("PMC") are authorized under special arrangement with Elsevier to process and post certain articles such as those funded by the National Institutes of Health under its Public Access policy (see elsevier.com for more detail on our policy).

    Articles accepted for publication in an Elsevier journal from authors who have indicated that the underlying research reported in their articles was supported by an NIH grant will be sent by Elsevier to PMC for public access posting 12 months after final publication. The version of the article provided by Elsevier will include peer-review comments incorporated by the author into the article. Because the NIH 'Public Access' policy is voluntary, authors may elect not to deposit such articles in PMC. If you wish to 'opt out' and not deposit to PMC, you may indicate this by sending an e-mail to NIHauthorrequest@elsevier.com.

    There will be no need for you to post your manuscript directly to PubMed Central, and any such posting is prohibited. Individual modifications to this general policy may apply to some Elsevier journals and to its society publishing partners.

    Take-home Message

    If you are submitting an Original Article or New Methods article, write 1 to 3 sentences interpreting (not summarizing) your work and placing it into context. What is the significance and what is the most important concept from your study for readers? What are the implications?

    Author Contributions

    Each submission must include an uploaded file outlining the contribution(s) that each author made toward the production of the article.

    Product and Drug Names

    Generic drug names should be used; trade names may beinserted in parentheses after the initial mention of the drug.Product names should be treated similarly, listing the manufacturer'sname, city, and state in parentheses. Do not put product or drug names in the title or the abstract of the article.

    Laboratory values should be presented in SI units. Forconversion from non-SI units seehttp://www.techexpo.com/techdata/techcntr.html. After laboratory values, normalvalues should be presented in parentheses in the text. A separate Word file listing all abbreviations and acronyms will need to be uploaded during the submission process.

    Abbreviations and Acronyms

    Spell out abbreviations and acronyms the first time the terms appear inthe text. You may follow the list of standard abbreviationsfound in the AMA Manual of Style, 10th edition.6

    Statistics

    • All studies reporting levels of significance must includethe sample size calculation and power used in that calculation.Justification for deviating from calculated samplesizes must be addressed.
    • Statistical techniques that do not appear in the publishedliterature should be presented as an appendix. All but themost standard tests should be referenced.
    • For reporting means, standard deviations, and standarderror, the following format should be used: "mean (SD)"and "mean ± SE." For reporting medians, the values ofthe interquartile range (IQR) and those of the rangeshould be given.
    • Report levels of significance for all comparisons made,whether significant or not, with P-values or confidenceintervals.
    • Papers that overstate the level of significance of findingsdue to multiple comparisons must be adjusted statisticallyand the results and discussion presented only withrespect to the corrected findings. The problem may beavoided through the use of multivariate methods; however,significance levels may be corrected with post-hoctests, such as Bonferroni's method. Multiple comparisonsof data from a single data set typically can occur in eitherof the two following situations: repeated measurementsof a single variable are tested over time, or several correlatedvariables are used in different tests of hypotheses.
    • Interpretation of results of regression analyses requiresthat units of continuous variables as well as categories ofdiscrete or ordinal variables be specified. Additionally, forlogistic regression and Cox regression analyses, the baselineor reference category of discrete or ordinal variablesmust also be given.

    Figures and Tables

    Figures (including color photographs) are published withoutcharge to authors.

    • Instructions for creating figures can be found below andat http://ees.elsevier.com/gie/ .
    • It is crucial that you create your figures at the correct resolutionbefore uploading them to the EESwebsite. For step-by-step instructions (with screenshotsof common graphics applications for PC or Mac users) onhow to create your figures at the proper resolution, see"Application guidelines" at http://authors.elsevier.com .For best results, please follow these guidelines carefully.
    • Figure images should be provided in EPS or TIF format. Graphics software such as Photoshop and Illustrator(not presentation software such as PowerPoint, CorelDraw,or Harvard Graphics) should be used to create the figures.
    • Illustrations should be saved at the highest resolution settingand sized as close to a column width (3 to 4 inches)as possible.
    • Upload each part of each figure separately in EES. Do not label figures with numbers or letters; the compositor will use a standardized font. Do be sure to name the figure file with the correct figure number and letter (e.g., Figure 1A). Do not make the figure legend part of the figure tiff file; figure legends must be placed at the end of the Word text file.
    • Use the colors from our "Figure Color Scheme," located at http://www.giejournal.org/content/figure_color_scheme, to add color to your figure charts and graphs (not tables).
    • Legends should be typed at the end of the text document andinclude enough information so that figures can be interpretedwithout reference to the text. Give staining andmagnification for photomicrographs of histologic slides.
    • Tables should be Word documents and should be placed at the end of the text Word document. All tables and figures must be cited in the text in consecutive order. Do not add color to tables; standardized color is added by the compositor.
    • At the discretion of the Editor, images and tables may appear in theprint version of the Journal, the electronic version, or both.
    • Random figures will be checked for image manipulation.

    Video/Computer Graphics

    • Videos and computer graphics (ie, slide presentations with or without animation) can be submitted through EES. If the file is too large to upload into EES, please email the GIE Editorial Office at gie@asge.org for special uploading instructions. Please indicate the video component on the submission cover page.
    • All videos or graphics submitted must be of the highestquality possible.
    • Submissions of videos that were originally recordedthrough the S-video or RGB outputs of the endoscopeprocessor are desired.
    • Gastrointestinal Endoscopy may edit any video or computergraphics. Reviewers, following the usual policy withillustrations, may suggest changes in the video or computergraphic.
    • A sound track is highly recommended, but not required.
    • Each video file must be less than 100 MB in size. If the file is larger than 100 MB, you will need to break it up into two or more smaller files.
    • Maximum cumulative length of videos or computergraphics is 8 minutes, and materials may be divided intoseveral smaller clips not to exceed 8 minutes in total. Ifthe video or animation is divided into several clips, eachclip should be identified at the beginning of the section(eg, Video Clip 1, Graphic 1) and on the disk. Severalvideos/graphics may be on the same disk, but if they areseparate clips, they must be saved as separate files. Whenneeded, use of simple transitions, eg, fade in/out dissolve,dip to color dissolve, are suggested.
    • Concise legends (typed on a separate page) must accompanyeach video clip or computer graphic presentation.
    • The following formats for video will be accepted: MPEG-1or MPEG-2 (.mpg), Quicktime (.mov), or CompuserveGIF (.gif). Please contact the publisher about the use ofother formats.
    • A graphic will be used in the text to indicate the locationof a video clip or computer graphic component.Videos/computer graphics for accepted manuscripts willnot be returned, nor will they be accepted separatelyfrom a rejected manuscript.
    • If the article is accepted for publication, the video will bedigitized and permanently archived on the GastrointestinalEndoscopy website (http://www.giejournal.org ).

    References

    • References must be cited in the text in consecutive orderand identified by superscript numbers.
    • It is the author's responsibility to check the accuracy of allreferences by verifying them against the original documents.Citations can be verified by using PubMed'sCitation Matcher (http://www.ncbi.nlm.nih.gov/entrez/query/static/citmatch.html ).
    • Examples of correct forms of reference, in accordancewith Uniform Requirements for Manuscripts Submittedto Biomedical Journals,1 are given in the online submissioninstructions.
