Swim lanes illustrating the 26 patients on the trial. Blue bars
represent time on abiraterone plus prednisone. Diamonds represent
progression to abiraterone plus prednisone (biochemical in yellow,
biochemical+radiological in brown) and starting date on AA+D (switch). Red
bars represent time to biochemical progression after switch. Green bars
represent time between biochemical progression and radiological or
clinical progression-free survival. AA+P, abiraterone plus prednisone;
bPFS, biochemical progression-free survival; rPFS, radiolographic
progression-free survival; cPFS, clinical progression-free survival; PSA
PD, biochemical progression; RX PD, radiological progression
