Submission Checklists


The corresponding author must give written assurance that neither the submitted material nor its portions thereof have been published previously or are under consideration for publication by this or other journals.


All authors must have made a significant intellectual contribution to the manuscript according to the criteria formulated by the International Committee of Medical Journal Editors. Each author should have participated sufficiently in the work to take public responsibility for the content. Authorship credits should be based only on substantial contributions to: (a) conception and design, or analysis and interpretation of data; (b) drafting the article or revising it critically for important intellectual content; and (c) final approval of the version to be published.
Participation solely in the acquisition of funds or the collection of data does not justify authorship. General supervision of the research group is not sufficient for authorship. The role played by each author should be described on the cover page (eg, in planning and/or conducting the study, collecting and/or interpreting data, and/or drafting the manuscript). The corresponding author is responsible for all aspects of the manuscript.
All authors (necessarily first author and corresponding author) are required to provide his/her "Open Researcher and Contributor ID (ORCID)," when submitting a manuscript to Journal of Neurogastroenterology and Motility. During the submission process, authors will have the option to either create an ORCID ID or associate an existing ORCID ID to their account. To learn more about ORCID, please visit https://orcid. org/about.
Any changes to the list of authors after submission, such as a change in the order of the authors or the deletion or addition of authors, need to be approved, following the submission of a letter requesting the change signed by all listed authors and from the author(s) to be removed or added. Such changes should be explained in writing to the editor in a letter or email from the corresponding author.
It is the responsibility of the authors to determine the order of authorship. Journal of Neurogastroenterology and Motility will not and cannot take any part in adjudicating authorship disputes.


In view of copyright laws, accepted papers must be accompanied by completed assignment forms. These forms are available on the website http://www.jnmjournal.org/file/Copyright_form.pdf. Papers will only be published once the copyright is completed. The authors grant the Korean Society of Neurogastroenterology and Motility to own the full copyright of the final version of the paper by copyright transfer with sign of all authors.


Acceptance of a manuscript in the Journal of Neurogastroenterology and Motility is determined through a rigorous peer-reviewing process. After the Editor-in-Chief and Executive editors assign an editor, the assigned editor sends the manuscript to 2 or more referees (except Editorials and Letters to the Editor) for peer-review. The assigned referees review the manuscript and their review results are reported to the Editor-in-Chief. Finally, the Editor-in-Chief notifies the review results to the corresponding author(s). If there is any objection to the review results, corresponding author(s) can appeal within 60 days after being notified. The Editor-in-Chief has the obligation to notify the results after one more review.


Submissions should be uploaded as Word or rich text format (rtf) documents. The entire article (including tables) should be supplied as a single file; only the electronic figures should be supplied as separate files. The manuscript must be written with double-line spacing and 3 cm margins on A4 sized format consecutively, beginning from the title page. Please include line numbers in your MS word manuscript to help reviewers refer to specific lines of the paper when they make their comments. All measurements should be in metric units.

    Each table must be simple and typed on a separate page with its heading above it. Explanatory matter is placed in footnotes below the tabular matter and not included in the heading. All non-standard abbreviations are explained in the footnotes.
    Footnotes should be indicated by superscripts a, b and c etc. The word "number" should be abbreviated as "n" to express the number of samples or subjects. For example, it should be written as (n=24). Statistical measures such as SD or SE(M) should be identified. Vertical rules and horizontal rules between entries should be omitted. Each table is referred in the text consecutively and numbered according to order of citation. The tables and its legend/footnotes should be understandable without reference to the text. The order of footnotes is as follows; after it is indicated by superscript a, b and c etc, then the abbreviation is explained. For example, IBS, irritable bowel syndrome; CNSD, chronic non-specific diarrhea. The last one is used for statistics.

    Figure legends

    Figure legends should be typed double-spaced on a separate sheet following Figure 1 or Figure 2. Symbols, arrows and letters indicating parts of illustrations should be explained in the legend. Each figure should be referred in the text consecutively as Fig. 1 or Fig. 2 in parenthesis and should be numbered according to order of citation. If figure is indicated in the sentence without the parenthesis, then it should be described as Figure 1.


    If a figure consisted of at least 2 sections, each figure should be listed as A, B or C in the upper left corner of each figure. The statistical difference (P-value) should be expressed as three digits below zero. If direct indication is difficult to express in the figure, then *, **, *** may be used. Theses asterisks should be explained in the figure legend. Figure format is individualized as follows: photographic images should be submitted in TIFF, JPG (JPEG), PNG, and GIF format with the original highresolution. It should have a minimum width of 100 mm and a minimum resolution of 300 dpi. Neither compression nor change of the color mode should be made. Linearts (graphs and illustrations) should be submitted in native PPT (preferred) including editable figure elements, vector files, or TIFF files (at least 300 dpi with a minimum width of 100 mm).

    Supplementary materials

    Supplementary material is peer reviewed material directly relevant to the conclusion of an article that is not included in the printed version owing to space or format constraints. It is posted on the journal's website and linked to the article when the article is published, and may consist of data files, figures, videos or extensive tables. The printed article must be complete and self-explanatory without the supplementary information. Supplementary material enhances a reader's understanding of the paper but may not be essential to the reader's understanding.
    When submitting supplementary material, ensure that you upload them using the "Supplemental File Upload." Supplementary material should be cited in the article text as "Supplementary Fig. 1, Supplementary Table 1 or Supplementary Materials and Methods etc." A legend for each figure, table, video, or other data should be included within the submitted file. All video files submitted must be of the highest quality possible. Any editing of the video is the responsibility of the author(s). Acceptable video file formats are: MPEG-1 or MPEG-2 (.mpg), Quicktime (.mov), Microsoft (.avi), or CompuServe GIF (.gif). Maximum video length is 5 minutes, and maximum file size is 160 MB. Concise legends must accompany each video in the text file.
