Kaplan–Meier plot for progression-free survival by investigator assessment. Patients without documented progression were censored at the date of their last tumour assessment. Crosses denote censoring events. At the cut-off date for 3-year analysis, 53 patients (82.8%) in the nintedanib group and 27 (84.4%) in the sunitinib group had progressed or died. Hazard ratio and confidence intervals for the overall treatment groups were obtained from Cox proportional hazards models stratified by Motzer risk score and previous surgery. Abbreviations: CI=confidence interval; HR=hazard ratio.
