Competing Interests

All authors have read the journal’s policy, and the authors of this manuscript have no financial competing interests. AA, SMW, and MC are employees of Public Citizen, a Washington, D.C.-based nonprofit consumer advocacy organization that has long worked on issues related to medical board oversight and physician accountability. Thus, these authors may be seen to have an intellectual competing interest. REO has no competing interests and received no compensation from Public Citizen for work on this paper, but he would like to disclose that he was Associate Director for Research and Dispute of the Data Banks before his retirement in 2008. In that capacity he designed the public-use NPDB file used in this study.
