Comparing optimum sensitivities and specificities of the two models
| Models | Sensitivity (%) | Specificity (%) | Positive predictivevalue (%) | Negative predictivevalue (%) |
| Model 1 (cutoff 0.15) | 76 (46 to 95) | 84 (72 to 92) | 53 (25 to 75) | 94 (84 to 99) |
| Model 2 (cutoff 0.3) | 82 (48 to 98) | 96 (87 to 99) | 82 (48 to 98) | 96 (87 to 99) |
Note: 95% CI.
