RT Journal Article SR Electronic T1 Editorial - Interpretation of Metaanalyses: Pitfalls Should Be More Widely Recognized JF The Journal of Rheumatology JO J Rheumatol FD The Journal of Rheumatology SP jrheum.111420 DO 10.3899/jrheum.111420 A1 Yves E. Henrotin YR 2012 UL http://www.jrheum.org/content/early/2012/02/28/jrheum.111420.abstract AB On the basis of metaanalysis of randomized studies assessing the symptoms and radiological progression of patients with osteoarthritis (OA), investigators have concluded that health authorities and health insurers should not cover the costs of glucosamine and chondroitin, and new prescriptions to patients who have not received treatment should be discouraged. This conclusion has the potential to change current management of OA mainly in Europe, where these compounds are prescribed drugs. But should metaanalysis be considered the ultimate level of evidence and sole support for these conclusions? This editorial addresses this question.
