| Variable | Cut-off | AUC (95% CI) | Sensitivity | Specificity |
|---|---|---|---|---|
| RPR | 0.109 | 0.728 (0.709-0.747) | 0.588 | 0.777 |
| RDW | 16.8 | 0.656 (0.636-0.677) | 0.524 | 0.703 |
| Platelet | 0.006 | 0.628 (0.606-0.649) | 0.513 | 0.700 |
| SOFA | 7.0 | 0.605 (0.584-0.626) | 0.536 | 0.615 |
| SAPS II | 49.0 | 0.610 (0.589-0.631) | 0.503 | 0.679 |
AUC: area under the curve; CI: confidence interval; RPR: red cell distribution width to platelet ratio; RDW: red cell distribution width; SOFA: sequential organ failure assessment; SAPS II: simplified acute physiology score II.
