To determine possible predictive factors for differential response to treatment, we performed a Fisher exact test for sex, liver cirrhosis, low platelet count (=below 150,000/μL), low white blood cell count (below 4000/μL), high baseline HDV viremia (>500,000 IU/mL), and high level of liver inflammation (ALT >100 U/L). The gene discussed is GPT; the disease is cirrhosis of liver.
