Table 5. ROC Analysis Indicating Various Cut-Off Values and Diagnostic Performance for Differentiating Patients with SLD from Other Patient Groups.

	AUROC (95% CI)	Cut-Off Reduction Rate	Sensitivity (%)	Specificity (%)
SLD vs. NLF	0.74 (0.63–0.83)	1.60	70.0 (50.6–85.3)	70.0 (55.4–82.1)
SLD vs. NLF and MLD	0.69 (0.63–0.75)	1.60	70.0 (50.6–85.3)	62.7 (55.5–69.5)

AUROC = area under the ROC curve, CI = confidence interval, MLD = mild liver disease, NLF = normal liver function, ROC = receiver operating characteristic, SLD =severe liver disease
