AUC, area under the receiving operator curve; CI, confidence interval; SD, standard deviation; TBS, trabecular bone score; BMD, bone mineral density mineral density; LS, lumbar spine; TH, total hip; FN, femoral neck. Statistically significant improvement in the AUC compared with the model predicting from either a low TBS or FN-BMD.
