Conflicts of interest (COI)may influence medical literature. However, it is still unclear whether medical journals have consistent policies for defining and soliciting COI disclosures. This study aims to determine the prevalence of author COI policies, requirements for signed disclosure statements, and variability in COI definitions among medical journals. Results show that of 256 journals, 89% had author COI policies, 54% percent required authors to sign a disclosure statement, and 77% provided definitions of COI. Conclusions show that in 2008, most medical journals with relatively high impact factors had author COI policies available for public review. Among journals, there was substantial variation in policies for solicitation of author COIs and in definitions of COI.
