Kaplan-Meier Estimate of Progression-Free Survival. Displayed are first-line (A) and second-line (B) progression-free survival in Arm A (Cap+Bev/Eve+Exe) and Arm B (Eve+Exe/Cap+Bev) in the ITT population. First-line and second-line progression-free survival were defined as the time from start of first-line / second-line therapy to progression or death due to any cause prior to start of new therapy, respectively. Patients without progression or death were censored at the date of last tumor evaluation in first-line / second-line therapy, respectively. N = number; PFS = progression-free survival; CI = confidence interval
