| Test variables | AUC (95%CI) | P value | Specificity (%) | Sensitivity (%) |
|---|---|---|---|---|
| PCT0h | 0.743 (0.661, 0.826) | 78.00 | 70.50 | |
| NLR0h | 0.756 (0.686, 0.825) | 92.13 | 38.36 | |
| PCT48h | 0.769 (0.702, 0.836) | 94.08 | 32.23 | |
| NLR48h | 0.682 (0.606, 0.758) | 81.25 | 41.09 | |
| ΔPCT | 0.834 (0.778, 0.891) | 75.03 | 80.98 | |
| ΔNLR | 0.852 (0.797, 0.908) | 76.98 | 83.82 | |
| ΔPCT+ΔNLR | 0.937 (0.905, 0.970) | 92.80 | 80.02 | |
| AUC – area under curve; NLR – neutrophil-to-lymphocyte ratio; PCT – procalcitonin; NLR0h – NLR at 0 hours; NLR48h – NLR at 48 hours; PCT0h – PCT at 0 hours; PCT48h – PCT at 48 hours. | ||||
