Diagnostic values of variables and results of receiver operating curve analysis.

Variables	Cut-off	Diagnostic values					ROC analysis			Odds ratio
		Sensitivity	Specificity	PPV	NPV	Accuracy	Area (SE)	%95 CI	P	Odds ratio	%95 CI	P
NLR	3.26	48.6%	88.2%	81.8%	61.2%	67.6%	0.698 (0.063)	0.575–0.821	.004	7105	2084–24.221	.001

CI = confidence interval, NPV = negative predictive value, P = statistical significance, PPV = positive predictive value, ROC = receiver operating curve, SE = standard error.
