Kaplan-Meier analysis of PFS in patients with hepatocellular carcinoma treated with atezolizumab plus bevacizumab in the high-level and low-level CD8+ tumor-infiltrating lymphocytes groups. Significant differences in PFS were determined by the log-rank test. The time 0 was defined as the date of atezolizumab plus bevacizumab administration.
