* Variables with statistically significant differences in univariate analysis and included in multivariate analysis for adjustment.
Model 1: multivariate analysis with baseline characteristics for original patients.
Model 2: multivariate analysis with baseline characteristics for patients after PSM.
Model 3: multivariate analysis with propensity score for patients after PSM.
HR, hazard ratio; CI, confidence interval; AST, aspartate aminotransferase; ALT, alamine aminotransferase; PLT, platelet count; BUN, blood urea nitrogen; AFP, alpha-fetoprotein.
