59, 41, and 16 of the abiraterone, enzalutamide and docetaxel cohorts had received the cohort-defining drug in the first line and these numbers defined the size of an additional 3:1 cohort. 177 (59 × 3), 123 (41 × 3) 48 (16 × 3) for the abiraterone, enzalutamide and docetaxel cohort, respectively.
No matches were found for one patient, thus only N = 47 was selected from the reference cohort.
p-values in each case are obtained by comparing the g-rates of a reference cohort to the olaparib cohort.
These p-values come from Wilcoxon rank-sum test.
