1. Authorship
An author must have made substantial contributions to all of the following categories established by the ICMJE: (1) conception and design, acquisition of data, or analysis and interpretation of data, (2) drafting the article or revising it critically for important intellectual content, (3) final approval of the version to be published, and (4) agreeing to be accountable for all aspects of the work to ensure that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved. Those who meet some, but not all authorship criteria should be mentioned in the acknowledgment section.
Changes to authorship (addition or deletion of author names or rearranging the order of authors) after the initial submission of a manuscript are possible during the review process; however, the corresponding author should submit a letter signed by all authors to the editor to explain the rationale for these modifications. All authors must complete the copyright assignment. Any revision to authorship is not permitted after acceptance of the manuscript.
The description of equal contributions, commonly indicated by co-first authors or co-corresponding authors, is permitted for up to two individuals. However, the equal contributions of the two authors should be explicitly explained to the editor in the cover letter submitted with the manuscript.
The corresponding author is primarily responsible for communicating with the journal throughout the publication process (manuscript submission, peer review, and publication). The editorial board may request the corresponding author for details regarding authorship, ethics committee approval, clinical trial registration documentation, and conflict of interest statements.
2. Originality, plagiarism and duplicate publication
3. Secondary publication
It is possible to republish manuscripts if they satisfy the conditions for secondary publication established by the ICMJE Recommendations (https://www.icmje.org/recommendations/browse/publishing-and-editorial-issues/overlapping-publications.html). Additionally, at the time of the second submission, the authors should clarify that all or parts of the manuscript have been published by another journal; the name of the journal should be mentioned on the title page and as a footnote.
At the time of manuscript submission, authors should submit a letter to the editor regarding any potential overlap with previously published material or material being evaluated for publication and should also highlight the differences between the manuscript submitted to the Korean J Helicobacter Up Gastrointest Res and other material published elsewhere. Copies of these materials should be provided to the editor to confirm any potential duplication and redundancy.
4. Statement of human and animal rights
All manuscripts that describe research performed using human subjects must be in compliance with the Declaration of Helsinki (https://www.wma.net/policy/). Researchers should obtain approval from the Institutional Review Board (IRB) and clearly state the research objectives and methods. Research subjects or their legal guardians should be informed regarding the adverse psychological or physical effects that may result from the research, and informed consent must be obtained.
Information that may reveal participants’ identities, such as name and initials, among other such sensitive data should be excluded from the research materials, including figures. If this is not possible, a written agreement should be obtained from the participants, and this statement should be included in the manuscript.
In animal studies, researchers should describe the measures adopted to minimize pain and discomfort to the animals, in accordance with The United States National Institutes of Health (NIH) Guide for the Care and Use of Laboratory Animals or equivalent institutional guidelines. Manuscripts that describe animal experiments must explicitly state that the study protocol was approved by the Institutional Animal Ethical Committee (IAEC) in accordance with the Korean Animal Protection Law or an equivalent standard.
Authors should clearly state that all experiments were performed in conformity with the Korean Animal Protection Law, “The Principle of Animal Experiment,” or an equivalent standard. The editor may request proof of informed consent and a certificate of IAEC approval.
5. Reviewer guideline
Reviewers should not release, copy, or cite manuscript content prior to publication. For details, please refer to https://www.helicojournal.org/authors/reviewers.php.
6. Registration of clinical trial research
It is recommended that any research that includes a clinical trial be registered with a primary national clinical trial registration site such as the Clinical Research Information Service (https://cris.nih.go.kr/), or other sites accredited by the World Health Organization International Clinical Trials Registry Platform (ICTRP) (https://www.who.int/clinical-trials-registry-platform) and ClinicalTrials.gov (http://clinicaltrials.gov), a service of the United States NIH.
7. Data sharing policy
The journal follows the data sharing policy described in “Data Sharing Statements for Clinical Trials: A Requirement of the International Committee of Medical Journal Editors.” The ICMJE’s policy regarding trial registration is explained on its webpage (http://www.icmje.org/recommendations/browse/publishing-and-editorial-issues/clinical-trial-registration.html#two).
Changes in the data-sharing plan after registration should be clearly mentioned in the statement submitted and published with the manuscript, and details should be updated in the registry records.
8. Conflict of interest statement
At the time of manuscript submission, authors should disclose any financial and personal relationships with other individuals or organizations that could affect their work. Examples of potential conflicts of interest include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. A potential conflict of interest should be disclosed in the manuscript, even when the authors are confident that their judgments have not affected preparation of the manuscript.
The disclosure form should be the same as the ICMJE Uniform Disclosure Form for Potential Conflicts of Interest (http://www.icmje.org/conflicts-of-interest/), and it should be submitted by the corresponding author through the online submission system after acceptance of the manuscript.
9. Managing research and publication misconduct
If the manuscript is not published in accordance with ethical policies, the authors will be notified, and sanctions may be imposed in accordance with the COPE guidelines (https://publicationethics.org/guidance/Flowcharts).
The journal operates a Research Ethics Council to consider research ethics and related issues. The Director of the Publication Committee of the Korean College of Helicobacter and Upper Gastrointestinal Research chairs the Council, and the Publication Committee determines the Council’s constitution.
The Research Ethics Council plays a key role in (1) reviewing research ethics issues (any fabrication, falsification, plagiarism, duplication, wrongful research paper author indication, or multiple/duplicate publication allegations) associated with publication of the journal and related papers (review articles, original articles, and others), and (2) reporting the results of the review to the Executive Committee of the Korean College of Helicobacter and Upper Gastrointestinal Research.
10. Management of cases requiring corrections, retractions, and editorial expressions of concern
In cases of publication misconduct, such as redundant (duplicate) publication, plagiarism, fraudulent or fabricated data, changes in authorship, an undisclosed conflict of interest, ethical concerns in a submitted manuscript, a reviewer who has appropriated an author’s idea or data, and complaints against editors, among other such issues, the editorial board will follow the COPE guidelines (https://publicationethics.org/guidance/Flowcharts). If any misconduct is proved, the authors will be notified and sanctions may be imposed.
The Editorial Board will continuously monitor and uphold publication ethics, which include publishing corrections, clarifications, retractions, and apologies when necessary, excluding plagiarized and fraudulent data, maintaining the integrity of academic records, and preventing business needs from compromising intellectual and ethical standards.
The Korean J Helicobacter Up Gastrointest Res will publish corrections as soon as possible, detailing the changes from and citing the original publication in cases in which errors are detected. The journal follows the ICMJE and COPE guidelines where applicable. An erratum refers to a production error related to the journal, and a corrigendum refers to an error attributable to authors. Authors who notice such errors should contact the journal’s editorial office.

(6) Whether the authors are familiar with the responsibilities and transparency of big data research. (7) Whether the authors are aware of guarantees of the study subjects’ right to request an explanation of the study and the right to access it.
1. The copyright of all manuscripts accepted for publication in the Korean J Helicobacter Up Gastrointest Res will be transferred to the Korean College of Helicobacter and Upper Gastrointestinal Research (https://www.hpylori.or.kr). The corresponding author should submit a “Copyright Transfer Form” through the online submission system after acceptance of the manuscript.
2. All articles published in the Korean J Helicobacter Up Gastrointest Res are distributed under the CC BY-NC license (https://creativecommons.org/licenses/by-nc/4.0/).
3. To use figures/tables/videos or any data from the Korean J Helicobacter Up Gastrointest Res for commercial purposes, the authors should submit a request for permission to the editorial office (kjhugr@kams.or.kr or hyplori@kams.or.kr); permission will be granted by the Editor-in-Chief if appropriate. Data may be used with appropriate citation of the original source in cases of non commercial use.
1. The authors should not submit their manuscript to other journals/publications once it is submitted to the Korean J Helicobacter Up Gastrointest Res. Authors may submit an article that has been published by a non-profit site (e.g., a university website, and arXiv, medRxiv, among others); however, this information should be specified in the cover letter, and the article should not be simultaneously submitted for peer review. Following publication in the Korean J Helicobacter Up Gastrointest Res, authors should update the non-profit site with the published article.
2. Following acceptance of an article, a public announcement of its content is not permitted prior to publication, except when it is essential in cases of public health emergencies; the editorial board may lift the restriction in such situations. Publication for commercial purposes is not permitted.
3. The Korean J Helicobacter Up Gastrointest Res is an openaccess journal that follows the CC BY-NC license (https://creativecommons.org/licenses/by-nc/4.0/). All articles are available free on the journal website (https://www.helicojournal.org); however, uploading articles to other databases without informing the editorial office is not permitted.
1. Submitted manuscripts are initially evaluated by the editorial office for completeness before the manuscript is assigned to a handling editor. Modifications/corrections may be requested at this stage before commencement of the peer review process.
2. The journal performs a double-blinded peer review of submitted manuscripts. Neither peer reviewers’ nor authors’ identities are shared with each other. At least two reviewers with relevant subject area expertise perform a blind review of all manuscripts. Authors suggest preferred reviewers at the time of manuscript submission; however, the eventual selection of reviewers is at the discretion of the Editor-in-Chief. Based on the results of the peer review, the editorial board decides whether the manuscript merits publication and may request manuscript revisions. If the editor is an author, the manuscript is handled by a different editor and the editor/author does not participate in the editorial evaluation or decision-making to publish the manuscript.
3. The editor’s decision regarding acceptance, rejection, or requests for major/minor revisions is communicated to the corresponding author. Following revision, manuscripts are reviewed to ensure that authors have complied with the journal’s instructions to authors. During the peer review process, editors may rephrase or format the manuscript but without altering the original meaning.
4. Reviewers are typically expected to complete the peer review within 2 weeks after accepting the invitation to review a manuscript. However, reviewers can request for an extension under unavoidable circumstances. Authors will be notified immediately by the editorial office in such an event, which may result in a delay in the review process. If the review process is unduly prolonged, authors may decide to withdraw their manuscript and resubmit it to another journal.
The authors may request withdrawal of their submitted manuscript at any time prior to formal acceptance of the article for publication. However, if a manuscript has already entered the “under review” status, it cannot be resubmitted after withdrawal. If however, the regular review schedule (2 weeks) is delayed, authors are immediately notified by the editorial office and under these circumstances, they may opt to withdraw their manuscript.
5. All manuscripts are peer-reviewed regardless of article type.
6. When requested, authors should revise the manuscript based on reviewers’ comments. Authors should upload their revised manuscript within one month of receiving the editorial decision. In the absence of a response from the corresponding author regarding the revised manuscript within one month, it is considered withdrawal of the manuscript, and the review process is terminated. For revisions, authors should mark the main document and supplementary tables using the track changes function in Microsoft Word, highlights, color fonts, and other such features and should suggest responses to reviewers.
7. After acceptance, the manuscript proofs will be sent to the corresponding author(s) for approval and these should be returned to the publisher within 48 working hours. The manuscript will be published after final confirmation from the corresponding author. Any errors detected in the manuscript thereafter are the responsibility of the author(s), and these should be corrected as a corrigendum.
The entire review process is performed through an online management system (https://submit.helicojournal.org). Only the corresponding author is permitted to submit a manuscript. The corresponding author must complete the copyright transfer agreement form after acceptance of the manuscript.
1. General principles of manuscript preparation
For detailed information on all manuscript types, please check the table titled ‘Types of articles’ in Instructions for Authors.
For clinical trials, the data-sharing statement should be added to the title page. The Korean J Helicobacter Up Gastrointest Res follows the ICMJE Recommendations for the data sharing statement policy (https://icmje.org/icmje-recommendations.pdf). Authors are required to identify the data, including patient information, a data dictionary that defines each field in the dataset, and supporting documentation (e.g., statistical/analytic code), which will be made available to others, including the following details: when, where, and how the data will be available (e.g., a link to a data repository), types of analyses permitted, and restrictions, if any, with regard to the use of the data. Authors are permitted to explain the rationale for not sharing data.
The corresponding author must include potential conflicts of interests for all authors. Conflicts of interests refer to financial and personal relationships with other individuals or organizations that could affect the research or data interpretation for manuscripts submitted to the Korean J Helicobacter Up Gastrointest Res. Even in the absence of a potential conflict of interest, authors should add this statement to the title page and also declare this information in the disclosure form. The disclosure form should be the same as the ICMJE Uniform Disclosure Form for Potential Conflicts of Interest and should be submitted via the online submission website after acceptance of the manuscript. If the editor is one of the co-authors, he/she will not participate in the editorial evaluation or decision-making for publication of the manuscript.
The contributions of all authors should be described based on the Contributor Roles Taxonomy (CRediT) authorship statement, which includes 14 roles: Conceptualization, Data curation, Formal analysis, Funding acquisition, Investigation, Methodology, Project administration, Resources, Software, Supervision, Validation, Visualization, Writing—original draft, and Writing—review & editing.
All authors must provide their ORCIDs on the title page at the time of initial submission of the manuscript.
Details of all financial support received for the study should be clearly declared in the Financial disclosure/funding sources section.
This section should mention all sources of support received for the research, including significant contributions of individuals who do not meet the authorship criteria.
2. Manuscript types
If the study involved an exclusive population, for example, participants of only one sex and/or gender, the authors should justify why, except in obvious cases (e.g., prostate cancer). Authors should describe determination of race or ethnicity and justify their relevance to the study. Even in the absence of differences based on sex/gender or race/ethnicity, authors should specify that there were no sex and/or gender or race/ethnicity differences.
