The following form must be submitted when uploading the article on the platform: https://www.permanyer.com/formulario-responsabilidades/#

The journal adheres to the “Uniform Requirements for Preparing Manuscripts Submitted to Biomedical Journals: Writing and Editing Biomedical Publications” in the most recent version published by the International Committee of Medical Journal Editors on its website http://www.icmje.org. regarding possible conflicts of interest, privacy and confidentiality, as well as human and animal rights as subjects of research. A copy of the informed consent will be requested in the case of studies with patients and clinical cases, as well as the approval of the Bioethics Committee of the corresponding institution, in the case of clinical and experimental studies.

The procedures in humans must adhere to the ethical standards of the Helsinki Declaration of 1975 (World Medical Association Declaration of Helsinki) Ethical principles for medical research involving human subjects. JAMA 2000; 284: 3043-5, as well as the agreement published by the Ministry of Health on January 26, 1982, and the Rules of the Ethics and Research Committee of the Institution where an original work was carried out. Studies in animals should follow similar guidelines (Institute of Laboratory Animal Resources, National Research Council, Guide for the care and use of laboratory animals, Washington, DC, National Academy Press, 1996). In relation to data confidentiality data, the way in which the anonymity of the participants and the privacy of their information have been protected must be informed.

To promote transparency and quality of research, authors will be asked to self-assess adherence to relevant international guidelines according to the type of study:

• • Reports of systematic reviews and meta-analyses should include a complete PRISMA checklist (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and a flow diagram to accompany the main text.
  • For other types of studies, consult the guidelines at the EQUATOR initiative (http://www.equator-network.org/).

  • Authors must also indicate in their “Methods” section whether there is a protocol for their systematic review and, if so, provide a copy of the protocol as supporting information and include the registration number in the abstract.

If your article is a systematic review or a meta-analysis, you must:

• • Indicate this in your cover letter.
  • Include the PRISMA flow diagram as Fig. 1 (required where applicable).

  • Include the PRISMA checklist as supporting information.

COPYRIGHT

Submitted manuscripts must be accompanied by a signed letter from all authors stating that the work has not been previously published or submitted elsewhere, that there is no conflict of interest, and that, if accepted, copyright is transferred to Asociación Mexicana de Gastroenterología, A.C.

EDITORIAL PROCESS

The editorial process consists of 6 stages:

1. Reception of the manuscript (indeterminate, depending on whether the author meets the requirements): its objective is to verify that the manuscript complies with the specifications of these instructions for authors and that the submitted documentation is complete.
2. Initial editorial review (maximum 5 business days): its objective is to corroborate the relevance, timeliness, originality, and scientific contribution of the manuscript, as well as the methodological and statistical soundness of the study. At this time, it will be submitted to an electronic plagiarism detection system. Derived from this, a rejected opinion may be obtained, or it will be sent for review by peer researchers.
3. Review by peer researchers (maximum 30 business days): the opinion of at least two experts in the area in question will be obtained, who will evaluate the technical and methodological aspects of the investigation.
4. Editorial review (maximum 7 business days): its objective is to make a decision based on the opinion of peer reviewers. The opinion can be rejected, major changes, minor changes or accepted. In the case of major or minor changes, it will be submitted again for evaluation by the initial peer reviewers.
5. Final edition (6 weeks): its objective is the technical and linguistic edition (and translation), layout of galleys, DOI assignment, and correction by the author.

6. Advanced publication: All manuscripts will be published ahead of print on the journal’s website as soon as they complete the editing process, until they are incorporated into a final issue of the journal.

PRINT PROOFS (PDF) OF ACCEPTED ARTICLES
