| Parameter | Cutoff | AUC | Sensitivity | Specificity | PPV | NPV | PLR | NLR | DA |
| (95%CI) | (%) | (%) | (%) | (%) | (%) | ||||
| White blood cell count | 10.6 × 109/μL | 0.87 (0.84-0.91) | 73.1 | 94 | 97.1 | 56.0 | 12.1 | 0.3 | 78 |
| Neutrophil | 69.85% | 0.87 (0.84-0.91) | 70.0 | 96 | 97.9 | 54.2 | 23.0 | 0.3 | 76 |
| Mean platelet volume | 8.98 fL | 0.62 (0.55-0.68) | 29.5 | 49 | 61.1 | 20.1 | 0.5 | 4.5 | 34 |
| Platelet distribution width | 32.15% | 0.95 (0.92-0.98) | 97.1 | 93 | 97.4 | 92.1 | 13.8 | 0.0 | 96 |
AUC: Area under the receiver operating characteristic curve; DA: Diagnostic accuracy; NLR: Negative likelihood ratio; NPV: Negative predictive value; PLR: Positive likelihood ratio; PPV: Positive predictive value.
