Having one of the following characteristics: (1) serum alanine aminotransferase (ALT) over two times upper limit of normal (ULN); (2) hepatitis B virus (HBV) DNA ≥ 20000 IU/mL for hepatitis B e antigen (HBeAg) (+) patients; or (3) HBV DNA ≥ 2000 IU/mL for HBeAg (-) patients. ANOVA was performed to compare age difference between cohort 1 vs cohort 2; χ2 test was conducted to compare male (%), insurance type (%) and disease status between cohort 1 vs cohort 2.
b
P < 0.01, cohort 1 vs cohort 2.
