Competing interest is anything that interferes with, or could reasonably be perceived as interfering with, the full and objective presentation, peer review, editorial decision making, or publication of research or non-research articles submitted to one of the journals. Competing interests can be financial or non-financial, professional, or personal. Competing interests can arise in relationship to an organization or another person.
The editors may decide not to publish a paper if they believe the competing interests declared by the authors or funders are such that they may have compromised the objectivity or validity of the research, analyses, or interpretations presented in the paper. With respect to commissioned or other non-research articles, editors do not commission or publish any such article, which comments on or reviews research findings or other topics, if they are aware of a competing interest that in their judgment could introduce bias or the reasonable perception of bias.
