| Nigrovic Published Prediction Model (%, 95% Confidence Interval) | Sample Rule “A” (%, 95% Confidence Interval) | Sample Rule “B” (%, 95% Confidence Interval) | Sample Rule “C” - Best Model (%, 95% Confidence Interval) | |
|---|---|---|---|---|
| Sensitivity | 98 (94–100) | 97 (93–99) | 98 (94–100) | 98 (94–100) |
| Specificity | 72 (68–76) | 81 (77–84) | 72 (68–76) | 81 (77–84) |
| Positive predictive value | 44 (38–50) | 53 (46–60) | 44 (38–50) | 53 (46–60) |
| Negative predictive value | 99 (98–100) | 99 (98–100) | 99 (98–100) | 100* (98–100) |
Negative predictive value of sample rule C is 431/433, which was rounded to 100 from 99.5%.
