Table 4.

AUROC for different volatile organic compounds for classifying patients with NAFLD cirrhosis vs. those with non-cirrhotic NAFLD.

Volatile organic compounds	AUROC (95% CI)	p value
Dimethyl sulfide	0.87 (0.74–1.00)	<0.001
D-limonene	0.83 (0.68–0.98)	0.002
Acetone	0.81 (0.63–0.99)	0.005

Discrimination used for internal model validation - ranking patient with NAFLD cirrhosis was measured by AUROC. AUROC, area under receiver operating characteristic; NAFLD, non-alcoholic fatty liver disease.
