Variable	Area under curve	Standard error	P value	95% CI
WBC (/mm3)	0.660	0.032	<0.001	0.598–0.723
NLR	0.713	0.030	<0.001	0.654–0.771
ESR (mm/hr)	0.611	0.033	<0.001	0.547–0.675
CRP (mg/L)	0.726	0.269	<0.001	0.669–0.783

CI, Confidence interval; WBC, white blood cell; NLR, neutrophil-lymphocyte ratio; ESR, erythrocyte sedimentation rate; CRP, C-reactive protein.
