The authors must declare any personal or commercial relationship that may imply bias and therefore a conflict of interest in connection with a submitted PAPER. Conflicts of interest may be direct or indirect, including financial interest of the authors by the institution or company that sponsors the study; as well as jobs, scholarships, per diem payments, trips, consultancies, etc.

If the author has shares in the company or is employed by it either full or part time, it must be indicated in the conflict of interest statement. Failure to do so may result in penalties.

Announcing the sources of financial support for the study does not imply a conflict of interest.
