Authors without ORCID will be recognized as collaborators in the acknowledgments of the article. It is also necessary that each author has reflected the full name of their institutional affiliation, province and country. The name of each author may be accompanied by the professional title, their scientific degrees, their academic degrees, their teaching and/or research categories, as appropriate.
- The author for the correspondence and email address must be defined.
- Authors must provide the primary data records used if requested by the editors.
- The authorization of each of the people mentioned in the section of Acknowledgments must be shown.
- Clinical trials: Clinical trials must carry their proper registration number obtained in a Clinical Trials Registry. This number must be verifiable, so the source will appear. In addition, they must conform to the evaluation parameters expressed in the CONSORT international guide.
