AUROC for different volatile organic compounds for classifying patients with NAFLD cirrhosis vs. healthy participants.

Volatile organic compound	AUROC (95% CI)	p value
Styrene	0.37 (0.16–0.58)	0.239
Acetone	0.77 (0.58–0.95)	0.015
Isoprene	0.49 (0.27–0.72)	0.965
Dimethyl sulfide	0.94 (0.86–1.00)	<0.001
D-limonene	0.91 (0.79–1.00)	0.002
Acetophenone	0.40 (0.12–0.61)	0.36
Terpinene	0.34 (0.13–0.54)	0.13

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.
