Attributes as a diagnostic test of the risk scoring system that worked best to predict each major outcome.
| Thrombosis | Mechanical Ventilation | Death | Composite Outcome | |
|---|---|---|---|---|
| Scoring system (optimal cutoff point by the Youden’s index) | Inflammation-based risk scoring system (≥5 points) |
Obesity and Diabetes score (≥5 points) | Obesity and Diabetes score (≥7 points) | Obesity and Diabetes score (≥5 points) |
| Sensitivity | 56.2% (37.8 to 73.1) | 92.5% (83.8 to 96.9) | 78.8% (64.9 to 88.4) | 77.0% (67.1 to 84.7) |
