Fig. 3: The Kaplan-Meier curves for survival in both groups at investigators’ evaluation.

Kaplan-Meier curves of (A) progression-free survival and (B) overall survival. Survival outcomes were estimated using the Kaplan-Meier method and compared between groups with the two-sided log-rank test. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using the Cox proportional hazards model. NE, not estimable. Source data are provided as a Source Data file.
