| Positive if greater than or equal to* | Sensitivity | 1–Specificity |
| 0.000 | 1.000 | 1.000 |
| 1.5 (intermediate-risk group) | 1.000 | 0.392 |
| 2.5 (high-risk group) | 0.710 | 0.114 |
| 3.5 (very high-risk group) | 0.290 | 0.002 |
| 5.0 | 0.000 | 0.000 |
*The smallest cut-off value is the minimum observed test value plus 1. All the other cut-off values are the average of two consecutive ordered observed test values.
