Cardiff University is pleased to support this campaign. We strongly believe in using all available evidence, from clinical trials, to change and develop medical practice, in the spirit and the traditions of Cardiff’s first and most Illustrious clinical trialist, Sir Archie Cochrane. Clinical Trials conducted by our researchers have resulted in a number of changes to medical practice, or, in some instances, have demonstrated a lack of benefit for a new experimental treatment. We will continue to insist that all trials conducted by our own clinical researchers and Clinical Trials Units are published, and we urge all others to do the same. Cochrane would have been horrified by the notion that information, generated from patients who consented to enter a clinical trial, was being withheld, and there can be no justification, ever, for doing so.
