Disclosure and Conflict of Interests

Any conflict of interest should be declared by all authors. This may include grants or honorarium, credits, promotions, memberships, or any personal or professional relationships which may appear to influence the manuscript. Such competing interests are not unethical but should be declared.

Authors should state the conflict of interest clearly in the submission statement form. This statement should also appear at the end of the text before the references. If there are no conflicts of interests, the authors should state, “none to declare.”
