Fig. 2: Kaplan–Meier analysis of OS in the HR+ and HR− cohorts.

a,b, HR+ cohort (a) and HR− cohort (b). For the OS and PFS by investigator endpoints for the HR+ and all patient cohorts, the HR status is based on data collected using the interactive web-response and voice-response system at the time of randomization, which includes patients who were misstratified. The dashed lines depict the landmark OS rates at 24 and 36 months.
