Notes: Quantitative ultrasound is not a diagnostic tool for osteoporosis. The T-score generated by QUS is different from T-score based on BMD obtained from DEXA. Pertaining to this study, the term “normal” indicates a low risk for osteoporosis, “osteopenia” indicates a moderate risk for osteoporosis, and “osteoporosis” indicates a high risk for osteoporosis.

Abbreviations: BMD, bone mineral density; DEXA, dual-energy X-ray absorptiometry; QUS, quantitative ultrasound.
