Analgesics for Osteoarthritis—An Update
Rating the Strength of Evidence From the CER
Throughout this slide set, strength of evidence ratings are assigned to findings of the report. Strength of evidence is typically assigned to reviews of medical treatments after assessing four domains: risk of bias, consistency, directness, and precision. Although these categories were developed for assessing the strength of treatment studies, the domains apply also to studies of prevalence and screening. Available evidence for each KQ was assessed for each of these four domains; the domains were combined qualitatively to develop the strength of evidence for each KQ.
