The results of ROC curve analysis for bacterial infection diagnosis.

	AUC (95% CI)		Suggested cutoff	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)
WBC	0.694 (IC 95%: 0.585-0.803)	0.002	6635	65	65.5	78	50
CRP	0.745 (IC 95%: 0.635-0.855)	<.001	20	70	75	84	57
PCT	0.741 (IC 95%: 0.639-0.843)	<.001	0.5	45	96.6	97.5	59

WBC: white blood cells. CRP: C-reactive protein; PCT: procalcitonin; PPV: positive predictive value; NPV: negative predictive value.
