Financial disclosure and conflict of interest policy

Authors must disclose any commercial relationships, material or financial support received during the research, at the time of writing the article or its publication, or any potential financial interest in relation to the subject of their article that could give rise to a conflict of interest.

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

In the event of 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.
