Clinical Study
Osteoporosis among Fallers without Concomitant Fracture Identified in an Emergency Department: Frequencies and Risk Factors
Table 3
The ability of two selected factors to correctly identify fallers with osteoporosis. Sensitivity, specificity, positive predictive values (PPVs), and negative predictive values (NPVs).

Sensitivity = TP/(): ability to correctly identify osteoporotic fallers. Specificity = TN/(): ability to correctly exclude fallers with normal BMD/osteopenia. PPV = TP/(). NPV = TN/(). |
