Another Korean study that included 150 patients with chronic liver disease (mostly viral hepatitis and 9.5% liver steatosis) who underwent liver biopsy reported a progressive decrease in haptoglobin levels with increasing fibrosis stage and a significant negative correlation between haptoglobin and liver fibrosis stage (r = −0.50, p < 0.001) [53]. The gene discussed is HP; the disease is Hepatic fibrosis.
