Figure 3. Subgroup analyses for the impact of surgery type (LR/LT) on DSS.

Comparisons between the DSS for patients receiving LR and LT were conducted in subgroups stratified by clinicopathologic factors. LR was used as the reference group for adjusted HR (95%CI). The factors considered for the multivariable Cox regression model included year of diagnosis, age at diagnosis, sex, tumor grade, tumor size, AFP level, fibrosis score, race, and marriage status. Abbreviations: DSS, disease-specific survival; LR, liver resection; LT, liver transplantation; HR, hazard ratio; CI, confidence interval; AFP, alpha fetal protein.
