A conflict of interest happened when an author, or the author's employer or sponsor, has a financial, economic, legal, or professional relationship with another organization or with those who work there, which could affect the author's study. Consultancies, employment, grants, fees and honoraria, patents, royalties, ownership of stock or shares, and other financial arrangements are a few examples of potential conflicts of interest in regard to the document that has been submitted. The author must make a complete disclosure at the time of submission, and the editor will utilize this information to guide editorial choices. Authors could be requested, if necessary, to explain any potential conflicts of interest in a covering letter. The editor or peer reviewers may decide not to publish a manuscript due to a declared conflict of interest.
