Fig. 2: Kaplan–Meier estimates of survival.

a Overall survival in the per-protocol set (n = 46). b Progression-free survival in the per-protocol set (n = 46). c Overall survival in the intention-to-treat population (n = 49). d Progression-free survival in the intention-to-treat population (n = 49). Kaplan–Meier survival curves are shown with 95% confidence intervals (shaded areas). Source data are provided as a Source Data file.
