Re: All trials must be registered and the results published

Dear authors,

Please note Prayle, Hurley & Smyth, BMJ of Jan 3 2012 who report about compliance with mandatory reporting of clinical trial results on ClinTrials.gov, based on studies registered which completed in 2009. Overall reporting rate within one year after trial completion is 22% : 40% for industry trials versus 8% for other trials (Table 2). Ben Goldacre discusses these findings on page 53 of his book by the way, but it seems not in an entirely fair manner.

Best regards, Koen Torfs.
