Financial disclosure and conflict of interest policy

Authors must communicate any commercial ties, material or financial aid received during the research, at the time of writing the article or its publication, or any potential financial interest in relation to the topic of their article that could give rise to a conflict of interests.

If there is no source of funding, the writing must include the section that states: “The authors did not receive any sponsorship to carry out this study-article.” Authors who do not have any conflict of interest related to the subject of the work must also declare: “There is no any type of conflict of interest related to the subject of the work.” This information will be announced at the end of each collaboration, in a visible place.

In the event that there are Conflicts of Interest, the authors of the article must declare it in the corresponding section (Conflicts of Interest), and attach the declaration of Conflicts of Interest according to the model proposed by the ICMJE (https://www.icmje.org/downloads/coi_disclosure.docx). The information in the declaration must match that of the submitted manuscript.
