A: Quantitative assessment, using ultrastructural morphometry, of autophagic vesicles in hepatocytes from controls with no or mild abnormalities at liver histological examination (n = 8), patients with nonalcoholic steatohepatitis (NASH) or alcoholic liver disease (n = 4), chronic hepatitis B (n = 7), or chronic hepatitis C (n = 23). B: HCV genotype did not influence the number autophagic vesicles (n = 23). Box plots represent median, quartiles, and ranges. **P < 0.01. ns, not significant.
