Competing interests
You and all your co-authors must declare any competing interests that are relevant, or that could be perceived as relevant to the article. Competing interests can occur when you (or your employer, sponsor, or family/friends) have a financial, commercial, legal, or professional relationship with another organization, or with people working with them that could influence the research or interpretation of the research results.
Competing interests can be financial or non-financial. To ensure transparency, you should also declare any relationships that could be perceived by others as competing interests.
Authors are required to disclose this information in their manuscripts.
