Abstract
Evidence-Based Answer After starting therapy for osteoporosis, dual energy x-ray absorptiometry (DEXA) scan results do not directly correlate with fracture risk (SOR: A, meta-analysis). In asymptomatic postmenopausal women on therapy for osteoporosis, a repeat DEXA scan is probably not helpful for at least 3 years (SOR: C, disease-oriented evidence).
A significance statement is not available in the OpenAlex record.
