However, compared to patients with non-viral HCC, patients with viral HCC were younger (median age 63.5 vs. 68 years, P < 0.001) and were more likely to have cirrhosis (91.3% vs. 75.6%, P < 0.001) but also CP class A liver disease (71.8% vs. 57.3%, P = 0.025). The gene discussed is CP; the disease is Cirrhosis.
