Kesselheim AS, Lee JL, Avorn J et al. Conflict of interest in oncology publications. A survey of disclosure policies and statements. Cancer 2011, epub 29 June
Because eliminating potential conflicts of interest is essentially impossible, nearly all biomedical journals require authors to disclose funding for their work, as well as other relevant relationships that they, their families, or their institutions might hold when an article is submitted for publication. The authors examined the disclosures related to conflict of interest accompanying papers published in major oncology journals to compare the nature of requested information with information provided. This analysis revealed a wide range of disclosure policies and practices: most but not all of the journals required some disclosure of potential conflicts of interest, but related standards and definitions varied considerably.
