Summary of Findings Two systematic reviews of t’ai chi interventions on bone mineral density in postmenopausal women were found to have starkly opposing conclusions due to the choice of quality appraisal tool. The authors conclude that the use of the Jadad scale in one review was not only inadequate but also inappropriate for reviewing t’ai chi studies, potentially misleading researchers, clinicians and policymakers.
