  1. (1) Data are presented as mean ± standard deviation (SD), median (interquartile range [IQR]), or number (percentage [%]). (2) P-values were calculated using independent samples t-test for age, Mann-Whitney U test for continuous variables (presented as median [IQR]), and Chi-square test or Fisher’s exact test for categorical variables. (3) HBV, hepatitis B virus; AFP, alpha-fetoprotein; BCLC, Barcelona Clinic Liver Cancer. (4) The CD28⁻CD57⁺CD8⁺ T-cell proportion is presented as a percentage of CD3⁺CD8⁺ T cells. (5) Macrovascular invasion refers specifically to portal vein tumor thrombus. (6) A two-sided p-value < 0.05 was considered statistically significant.
