Table 3.
Performance of the STRATIFY score and FRAX™ score. Sensitivity and specificity of the scores to predict ICH were calculated (A), and AUC was calculated (B). AUC values generated by the STRATIFY score and FRAX™ score were compared
| A. Sensitivity and specificity | |||
|---|---|---|---|
| Events | Scores | Sensitivity | Specificity |
| Falls | STRATIFY | 0.533 | 0.791 |
| FRAX™ | 0.554 | 0.628 | |
| Major injuries after falls | STRATIFY | 0.532 | 0.781 |
| FRAX™ | 0.733 | 0.623 | |
| Peripheral fracture after falls | STRATIFY | 0.607 | 0.781 |
| FRAX™ | 0.778 | 0.623 | |
| Fracture after falls | STRATIFY | 0.545 | 0.781 |
| FRAX™ | 0.781 | 0.623 | |
| ICH after falls | STRATIFY | 0.545 | 0.780 |
| FRAX™ | 0.800 | 0.623 | |
| B. Area under the ROC | |||
|---|---|---|---|
| Events | STRATIFY | FRAX™ | p-value |
| Fall | 0.698 | 0.615 | <0.001 |
