Information for authors Submitted works must be unpublished. Original articles containing material previously published in other publications will not be accepted, unless they have been published as abstracts of less than 400 words. Manuscripts will be independently evaluated by two expert reviewers through a double-blind system (authors and reviewers remain confidential and anonymous). Authors may suggest the names of experts in the field whose experience qualifies them to evaluate the work (this can be done through the "Comments to the Editor" text box provided by this platform). Acceptance of the article will be based on its merits and the editorial policy of the journal, and will be decided by the Editorial Committee based on the reviewers' opinions. If the submitted work involves research on humans, it must have been conducted in accordance with the Declaration of Helsinki of 1975, and must have the informed consent of the patients or volunteers. Copyright is retained and the journal is guaranteed the right to be the first publication of the work. The GEN Journal is licensed under a Creative Commons 4.0, which allows others to share the work with acknowledgment of authorship and initial publication in this journal.

It must be attached in Word format (.doc, .docx), letter size, Arial font size 12, double-spaced, with numbered pages. Original articles Original articles must make a significant contribution to the field of clinical research. They cannot exceed 4,000 words and must be organized as follows: Title: must be brief and precise with a maximum of 15 words, without abbreviations; ordered from general to specific, expressing the content of the text and consistent with the International Classification of Diseases (WHO) to be registered in national and international indexes. A short subtitle (no more than 40 characters) may be included. The full names of the authors and the ORCID of each of them. Abstract: should not exceed 200 words and should be organized into four sections: Introduction, Patients and Methods, Results, and Conclusions. It should not contain abbreviations or bibliographic references and its content should be understandable without referring to any other text, table, or figure. Include no fewer than 3 and no more than 10 keywords using Health Sciences Descriptors. Abstract in English: constitutes an indispensable part of the manuscript. It must be preceded by the title of the work in English and must have the same content as the abstract in Spanish; at the end, the keywords should be included. Introduction: should concisely present the problem and the attempts made by other authors to solve it, citing the corresponding bibliographic references. Clearly state the objectives of the study, as well as the hypothesis to be tested. An extensive review of the topic is not necessary. Patients and Methods: should be brief but sufficiently clear to allow another researcher to repeat the work and/or validate its conclusions. Clearly describe the selection criteria for the patients studied. It is recommended that the procedures used or already published be cited only as bibliographic references. Describe the statistical methods in sufficient detail for the reader to verify the reported data. Results: should be presented clearly and concisely, highlighting the most relevant findings. Whenever possible, it is recommended to use tables that summarize findings, which will be referenced in the text. The measurements expressed in the work should follow the International System (SI) of units. Decimal figures should be written with a comma (,) and not a period (.). Conclusions: should mention the study's conclusions and recommendations when appropriate. Tables: a table is any arrangement of data in a structured format organized in rows and columns. Each table must be referenced in the text and accompanied by a legend that clearly explains its content, so it can be understood without reading the rest of the work. Tables should be editable and presented in a simple and clear format. Figures: figures include drawings, diagrams, and photographs. There must always be a reference in the text for each figure. Each figure should be accompanied by a legend that explains its content so that it can be understood without reading the body of the work. Each work is entitled to a maximum of 5 tables and 5 figures. Graphs should be presented in 2D and not in 3D. References: should be included in the text and numbered consecutively as they appear, with Arabic numerals in superscript; mention all authors when there are 6 or fewer, and if there are more than 6, mention the first three and add "et al."
