Independent factors	Cutoff value	Sensitivity	Specificity	AUC	P-value	95%CI
Neutrophil, %	73.75	0.750	0.900	0.888	0.000	0.831–0.945
CRP, mg/L	44.45	0.550	0.850	0.736	0.000	0.648–0.825
LDH, IU/L	590.0	0.763	0.475	0.611	0.048	0.503–0.719
Fer, ng/L	411.0	0.864	0.682	0.814	0.000	0.736–0.892

P value: the AUC value of the independent factors compared to ROC curve reference value 0.5

AUC Area under the ROC curve, Cut-off value The value on the ROC curve is closest to the upper right to take maximum sensitivity and specificity
