The OPEM requires all authors to disclose any financial conflict of interest that might be construed to influence the results or interpretation of their manuscipt. Authors must declare any such conflict in the cover letter accompanying the manuscript and in the Acknowledgments section of the manuscript itself. The corresponding author will be asked to sign a form on behalf of all the authors regarding potential conflicts of interest at the time of acceptance. As a guideline, any affiliation associated with a payment or financial benefit exceeding $10,000 p.a. or 5% ownership of a company or research funding by a company with related interests would constitute a conflict that must be declared. This policy applies to all submitted research manuscripts and review material. Examples of statement language include: AUTHOR is an employee and shareholder of COMPANY; AUTHOR is a founder of COMPANY and a member of its scientific advisory board; This work was supported in part by a grant from COMPANY.
