Collagen proportionate area correlates to hepatic venous pressure gradient in non-abstinent cirrhotic patients with alcoholic liver disease

Figure 2 Correlation between hepatic venous pressure gradient and fibrosis density measured by collagen proportionate area. A: Correlation between HVPG and fibrosis density measured by CPA in the whole group of patients; B: Subgroup analysis showing a positive correlation between CPA and HVPG restricted to active alcohol drinkers. HVPG: Hepatic venous pressure gradient; CPA: Collagen proportionate area.
