| Sensitivity, % (95% CI) | Specificity, % (95% CI) | Positive predictive value, % (95% CI) | Negative predictive value, % (95% CI) | C-statistic, % (95% CI) | |
| Surprise question | 45.5 (43.2 to 47.9) | 90.6 (90.1 to 91.0) | 30.4 (29.0 to 31.8) | 94.8 (94.6 to 95.1) | 0.680 (0.669 to 0.692) |
| PSCT | 45.8 (43.4 to 48.2) | 92.0 (91.6 to 92.4) | 34.1 (32.6 to 35.7) | 94.9 (94.7 to 95.2) | 0.689 (0.677 to 0.701) |
| Combination of surprise question with PCST | 59.2 (56.8 to 61.5) | 86.2 (85.8 to 86.7) | 28.0 (27.0 to 29.1) | 95.9 (95.7 to 96.1) | 0.739 (0.727 to 0.752) |
