From Lown Institute: “In the recently published papers from the COMPare project, researchers from the Centre for Evidence-Based Medicine at the University of Oxford set out to find out how prevalent outcome reporting errors are in major medical journals, and how these journals respond to criticism.
The COMPare study is the first to systematically analyze how journals respond to requests for corrections. Researchers analyzed all trials published over a period of six weeks in five top medical journals that endorse CONSORT [the Consolidated Standards of Reporting Trials] (the journals were JAMA, Annals of Internal Medicine, The BMJ, The New England Journal of Medicine, and The Lancet). They noted all trials that had an incorrectly reported outcome, and sent letters to the journals for each discrepancy that needed correcting. The results of this landmark trial should make us concerned about how medical journals are monitoring outcome reporting. Here’s why.”
