Time-varying Cox was applied for analysis. Virologic breakthrough was defined as HBV DNA . Minor virologic breakthrough was defined as HBV DNA . Univariable factors were analyzed with the Firth method. AST: aspartate aminotransferase; ALT: alanine aminotransferase; CI: confidence interval; HBV: hepatitis B virus; HR: hazard ratio; LC: liver cirrhosis.
