Estimates of mean sensitivity and specificity (with 95% CIs), overall and split by different body systems
| Body system | Mean sensitivity (95% CI) | Mean specificity (95% CI) |
| Overall | 73.3 (59.9 to 83.5) | 96.6 (92.6 to 98.4) |
| Neurological | 84.3 (70.8 to 92.2) | 96.7 (86.5 to 99.3) |
| Cardiothoracic | 52.1 (27.6 to 75.5) | 96.6 (86.8 to 99.2) |
| Abdominal | 78.4 (61.0 to 89.4) | 97.3 (88.9 to 99.4) |
| P value (neuro vs cardio) | 0.010 | 0.916 |
| P value (neuro vs abdom) | 0.498 | 0.819 |
| p-value (cardio vs abdom) | 0.059 | 0.731 |
