Figure 2. Correlation of CD8⁺ CTLs with prognosis in the entire cohort (n = 332).

Using the established CD8⁺ CTLs infiltrate status for Kaplan Meier survival analysis, results demonstrated that positive CD8⁺ CTLs infiltrate status were statistically significant associated with longer DFS (Log-rank test: P = 0.003; Fig. 2A) and longer OS (Log-rank test: P = 0.011; Fig. 2B).
