Overall survival
REGRESSION
Median overall survival in the evaluable population was 27.5 months (95% CI = 14.7 to 37.1). Median overall survival was 30.5 months (95% CI = 11.9 to 51.3) in MRI responders and 17.2 months (95% CI = 7.0 to 37.1) in MRI nonresponders. Overall survival, by MRI responseAssumption of proportional hazards does not hold for this response definition, so association was also tested using regression of the restricted mean survival times.
