Table 5. ROC to compare various variables for prediction of CAL.

	AUC	Cut-off value	Sensitivity	Specificity	PPV	NPV
PMN (%)	0.550	71.95	55.5	71.2	0.87	0.09
NT-proBNP (pg/dL)	0.530	709	41.2	70.5	0.88	0.10
CRP (mg/dL)	0.517	11.71	25.0	81.0	0.87	0.01
Albumin (g/dL)	0.464	4.75	98.0	4.0	0.90	0.20
Total bilirubin (g/dL)	0.500	1.13	84.0	21.0	0.90	0.14
AST (IU/L)	0.493	203.5	91.0	10.0	0.90	0.11
ALT (IU/L)	0.497	11.5	14.0	88.0	0.91	0.11

ALT = alanine aminotransferase; AST = aspartate aminotransferase; AUC = area under the curve; CAL = coronary artery lesion; CRP = C-reactive protein; NPV = negative predictive value; NT-proBNP = N-terminal-pro-brain natriuretic peptide; PMN = polymorphonuclear neutrophil; PPV = positive predictive value; ROC = receiver operating characteristic.
