ROC analysis of CAR, CRP, and ESR in the diagnosis of severe disease
| Parametre | Cut-off | Sensitivity (%) | Specificity (%) | PPV (%) | NPV (%) | AUC | p |
|---|---|---|---|---|---|---|---|
| CAR | 0.6 | 88.9 | 90.3 | 85.1 | 92.8 | 0.941 | 0.001 |
| CRP | 2 | 91.1 | 86.1 | 80.4 | 93.9 | 0.931 | 0.001 |
| Albumin | 3.6 | 91.1 | 70.8 | 66.1 | 92.7 | 0.883 | 0.001 |
| ESR | 36 | 88.4 | 84.6 | 79.2 | 91.7 | 0.888 | 0.001 |
CRP: C-reactive protein; CAR: CRP/Albumin ratio; ESR: Erythrocyte sedimentation rate; PPV: Positive predictive value; NPV: Negative predictive value; AUC: The area under the receiver operating characteristic.
