Cirrhosis	0.488	0.329–0.646	0.878
Number	0.534	0.375–0.693	0.678
Size	0.540	0.380–0.699	0.626
Encapsulation	0.501	0.342–0.661	0.986
Edmonson grade	0.525	0.366–0.683	0.759
MVI	0.549	0.389–0.709	0.545

AUC, area under the curve; HCC, hepatocellular carcinoma; ctDNA, circulating tumor DNA; MAF, mutant allele frequency; MVI, microvascular invasion.
