Competing Interests

EHP has a policy of full disclosure concerning  competing financial and nonfinancial interests.

1. Authors must disclose potential competing financial interests, including but not limited to grant support; employment (past, present, or firm offer of future); patents (pending or applied); payment for expert witness or testimony; personal financial interests by the authors, immediate family members, or institutional affiliations that may gain or lose financially through publication of the article; and forms of compensation, including travel funding, consultancies, board positions, patent and royalty arrangements, stock shares, or bonds. Diversified mutual funds or investment trusts do not constitute a competing financial interest. Authors employed by a for-profit, nonprofit, foundation, or advocacy group must also declare employment. Authors should carefully examine the wording of documents such as grants and contracts to determine whether there might be an actual or potential competing interest.
2. All potential competing interests occurring during the last 3 years should be reported.
3. As a condition of review and publication, authors must certify that their freedom to design, conduct, interpret, and publish research is not compromised by any controlling sponsor.
