A conflict of interest can be defined as a situation in which personal relationships (such as a friend, colleague, or family), work relationships (such as working for a competing company or the same organization), or financial influences (such as funding) influence anyone's judgment during the publication of the journal.

Authors must declare (within the article and to the editor-in-chief) any conflict of interest that may have affected their research (e.g., funding) or the decision to submit it to the journal. Reviewers must declare if they have any conflicts of interest that may influence their judgment of any article they review. Editors are excluded from any publishing decision in which they may have a conflict of interest.
