| Outline of Final Research Achievements |
We examined whether or not trabecular bone score (TBS) predicts the risk of incident vertebral fracture in community dwelling 890 women and 855 men. Prediction accuracy of TBS represented by area under ROC curve was 0.682 and 0.630 for women and men, respectively, which were significantly better than chance, but was not sufficient enough to use in clinical settings. The follow-up period was short in men and should be extended so as to be analyzed with a greater statistical power. In addition, prediction models incorporating risk factors other than TBS and bone density should be developed to improve their validity.
