GUIDELINES FOR FIGURES AND TABLES

• Figures: They are drawings, maps, photographic images, diagrams, statistical charts, schemes or any illustration different from a table. They should be numbered consecutively according to their first mention in the text. If the figure has been previously published elsewhere, the original source should be cited and the written permission for reproduction of the material presented. This authorization from the copyright owner is necessary; exceptions to copyright are documents of public domain. Photographic images should be sent as TIFF or JPG files with a resolution of at least 600 dpi or 300 pixels. Identifiable facial photographs should be edited to protect patient anonymity (Table 1).
• Tables: They should include the necessary information in both the title and content to understand them with no need to read the text. It is recommended to check that the data presented in the tables do not duplicate the results described elsewhere in the text. The tables should be submitted as Microsoft Word or Excel files (not as images), numbered consecutively and with Arabic numerals. They should only have horizontal lines to separate the heading from the body and, in no case, they should have vertical lines. Definitions of abbreviations and symbols used in the tables should be placed in a footnote below each table body. If a table includes data from another published or unpublished source, it is imperative to gain permission for using it and acknowledge that source as a footnote under the table (Table 1).

BIBLIOGRAPHIC REFERENCES

Bibliographic references should appear in the order the sources are cited in the text of the paper according to the Vancouver Citation Style and ICMJE Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals (ICMJE Recommendations) (https://www.nlm.nih.gov/bsd/uniform_requirements.html). Authors should only cite the sources used to write the text. Bibliographic references should be numbered consecutively in the order in which they are first mentioned in the text, using superscript Arabic numerals and in parentheses. If citing more than one reference at the same point, separate the numbers with commas, but use an N dash (–) to join the first and last numbers of a closed series. If a document has six (6) or more authors, provide the last name of the first six (6) with the abbreviation "et al." (roman font) (Table 1).

III. ETHICAL CONSIDERATIONS IN RESEARCH AND PUBLICATIONS

ETHICS IN RESEARCH

Horizonte Médico (Lima) journal meets current ethical standards for scientific research and publications, either during the review process or afterwards. For research studies conducted in humans, the manuscript should include a statement to confirm that the research protocol was previously approved by an institutional ethics committee and that it meets the World Medical Association (WMA) Declaration of Helsinki – Ethical Principles for Medical Research Involving Human Subjects (revised in 2013).

Approval from an institutional ethics committee is required in the following cases: research involving human subjects, human biological materials or potentially identifiable personal data (e.g., medical records).

Research using public domain secondary databases (systematic reviews, meta-analyses or bibliometric studies), public health programs (surveillance and assessment) and research on outbreaks or health emergencies do not require the approval of the institutional ethics committee.

The most common ethical misconducts in publications are plagiarism, honorary or ghost authorship, data manipulation, and attempt at duplicate or redundant publication. In order to detect plagiarism or similarity, Horizonte Médico (Lima) journal uses Turnitin software.

In the event of any doubt and/or dispute on that issue, it will be evaluated and solved by Horizonte Médico (Lima) journal’s Editorial Board, according to the following standards and international bodies: Declaration of Helsinki 2013, World Health Organization (WHO), Council for International Organization of Medical Sciences (CIOMS), American College of Epidemiology (ACE) Ethics Guidelines, Health Research Ethics Authority (HREA, Canada) and Committee on Publication Ethics (COPE) (www.publicationethics.org).

AUTHORSHIP CRITERIA

Horizonte Médico (Lima) journal’s Editorial Board follows ICMJE recommendations for attribution of authorship, which is based on the following criteria:

1. Substantial contributions to the conception or design of the work, or the acquisition, analysis or interpretation of data for the work.
2. Drafting the work or reviewing it critically for important intellectual content.
3. Final approval of the version to be published.
4. Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

Those designated as authors should meet all four (4) criteria, which will be specified in the Authorship Contribution section. According to the ICMJE, contributors just involved in the acquisition of funding, data collection or supervision of the research group are not considered authors and should be included in the Acknowledgement section.

CRediT (Contributor Roles Taxonomy) can be used to describe the roles played by manuscript contributors (https://credit.niso.org/) such as:

1. Conceptualization
2. Methodology
3. Writing – original draft
4. Writing – review and editing

IV. EDITORIAL PROCESS

Manuscripts will be submitted for consideration of the Editorial Board, which consists of a multidisciplinary team of experts who are members of renowned research institutions.

PRELIMINARY REVIEW

All manuscripts submitted to the journal undergo an originality analysis using an anti-plagiarism program that detects the level of authenticity and accepts up to a maximum of 15% similarity. During this preliminary review phase, the editorial coordinator may contact the corresponding author to request resubmission of the manuscript with the necessary corrections within 15 days.

Subsequently, the manuscript is referred to the editor or a member of the Editorial Board, who will determine its relevance to one or more thematic axes of the journal; otherwise, it is returned to the author.

PEER REVIEW

Manuscripts are initially evaluated according to Horizonte Médico (Lima) journal’s guidelines, which aim to ensure the quality and integrity of the manuscripts submitted for publication. Then, they are assessed by (internal and external) peer reviewers who are experts from the same field as the authors. Peer reviewers’ participation is always anonymous and ad honorem.

Peer review is conducted by double blind peer review—i.e., reviewers do not know the identity of the manuscripts’ authors, and authors do not know the identity of the reviewers.

Manuscripts submitted for the journal’s different sections—i.e., original articles, brief communications, review articles, case reports and opinion articles—are assessed by at least two (2) peer reviewers. In the case of manuscripts written in English, at least one (1) of the referees will be a native English speaker or a member of an institution from an English-speaking country.

Manuscripts submitted for sections such as the editorial, history, biosketch and letter to the editor are only evaluated by the Editorial Board, unless the evaluation of an external reviewer is required.

Peer reviewers’ grading may be as follows: a) The manuscript is recommended to be published with no modifications. b) The manuscript should be published after the implementation of some corrections and improvements. c) The manuscript is rejected for the moment, but it is recommended to make corrections and submit a new version. d) The manuscript is rejected with observations not subject to validation.

Based on the peer reviewers’ observations, the Editorial Board will decide if the manuscript is to be published or rejected, or if recommendations should be sent to the authors.

RESPONSE TO OBSERVATIONS

The author should submit the corrected version of the manuscript, indicating the modifications applied and answering the reviewers’ comments in thirty (30) days.

The Editorial Board has the authority to resend the corrected manuscript to the peer reviewer before considering its publication. If the recommendations have been favorably met, the manuscript will be published.

The average time of the editorial process, as from the reception of the manuscript to its publication, varies from two (2) to four (4) months.

FINAL PROCESS

Approved manuscripts will undergo a final editing process. Manuscripts in PDF format will be sent to the authors for their examination. They will be allowed to modify only the style and translation but not the content. Reviewed manuscripts should be returned by the authors during a period of seven (7) days; otherwise, the Editorial Board will consider the final version as accepted.

V. ADOPTION OF OPEN SCIENCE

In order to be in line with open science policies of scholarly communication and in accordance with SciELO Perú policies for the evaluation of scientific journals (2020), Horizonte Médico (Lima) journal reports that as of October 2021 and progressively:

Manuscripts previously deposited in preprint servers certified or recommended by the journal will be accepted.

Authors will be asked to include citations and references of data, program codes and other content underlying the articles’ texts. As an option, it is recommended that referenced contents be available in open access prior to or in parallel with the article publication.

Mechanisms to open the peer-review process will be allowed: initially, a single-blind peer review—i.e., the reviewer knows the author’s data—and then an open peer review will be used. Thus, if manuscripts submitted for peer review have preprints, the type of review will be differentiated.

For published preprints, the corresponding author should inform the journal that the research follows and complies with open science policies by using the Open Science Compliance Form (.docx). The form should be sent as an additional and complementary file to the manuscript and other documents requested by the journal through the online submission system.

The journal recommends using one of the following preprint servers according to the topic of the manuscript and the decision of all authors:

• SciELO Preprints (https://preprints.scielo.org)
• medRxiv (https://www.medrxiv.org)
• bioRxiv (https://www.biorxiv.org)
• arXiv (https://arxiv.org)
