Sensitivity and specificity of CgB and CgA values (cut-off value: CgB, 2.03 nmol/l; CgA, 47.1 ng/ml)

Positive biomarker	Number (n = 91)	AUC (95% CI)	Sensitivity	Specificity	P value
CgB	66	0.79 (0.71–0.85)	0.73	0.77	<0.0001*
CgA	72	0.78 (0.71–0.84)	0.79	0.64	<0.0001*

CgA, chromogranin A; CgB, chromogranin B; CI, confidence interval; AUC, area under the curve; *Statistically significant using Chi-square test.
