Performance of the Osteoporosis Self-Assessment Tool in ruling out low bone mineral density in postmenopausal women: a systematic review

Summary The Osteoporosis Self-Assessment Tool (OST) is a simple test that may be of clinical value to rule-out low bone mineral density. We performed a systematic review to assess its performance in postmenopausal women. We included 36 studies. OST performed moderately in ruling-out femoral neck T-score ≤ −2.5, but poorly in ruling-out lumbar spine T-score ≤ −2.5. Methodological study quality was generally low.
