Cutoff value, sensitivity and specificity

Variable	Cutoff value	Sensitivity	Specificity
The AUC of NLR, WBC, NEUT and LY are respectively 0.921 ± 0.028, 0.789±0.056, 0.821±0.052, 0.150±0.042. Obviously, NLR is the most advantageous index to predict the prognosis with high sensitivity and specificity(0.903, 0.839).
NLR	11.26	0.90	0.84
WBC	7.54	0.84	0.65
NEUT	6.87	0.87	0.73
LY	0.95	0.16	0.31
