Predictive values of parameters for bacterial infection in HFRS patients.

Variables at admission	AUC	P-value	Cut-off value	Sensitivity	Specificity	95% CI for AUC
						Lower	Upper
Lg PCT at admission	0.618	0.016	0.00	0.71	0.54	0.524	0.711
Neutrophils percentage at admission	0.639	0.005	67.47	0.68	0.59	0.550	0.729
Lymphocytes percentage at admission	0.651	0.002	18.51	0.67	0.59	0.563	0.740

AUC, area under the receiver operating characteristic (ROC) curve; CI, confidence interval; Lg PCT, procalcitonin after log10 transformation.
