F, degree of fibrosis using the new Inuyama classification (F0, no fibrosis; F1, portal fibrosis widening; F2, portal fibrosis widening with bridging fibrosis; F3, bridging fibrosis and lobular distortion; and F4, cirrhosis); HBV hepatitis B virus, HCV hepatitis C virus, NBNC (non-B, non-C). *Statistical significance
^aHCCs with a PTHR were identified in 7 patients with alcoholic liver disease, 3 patients with nonalcoholic steatohepatitis, and one patient with an unknown etiology
^bHCC without a PTHR was identified in one patient with alcoholic liver disease
