What was measured

EQ-5D was a standardized HRQOL questionnaire consisting of EQ-5D descriptive system and Visual Analogue Scale (VAS). EQ-5D descriptive system comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression measured on 3 levels (no problem, some problems \& severe problems) within a particular EQ-5D dimension. 5 dimensional 3-level system was converted into single index utility score. Possible values for single index utility score ranged from -0.594 (severe problems in all dimensions) to 1.0 (no problem in all dimensions) on scale where 1 represented best possible health state. EQ-5D VAS was used to record a participant's rating for his/her current health-related quality of life state and captured on a vertical VAS scale ranging from 0-100, where 0=worst imaginable health state and 100=best imaginable health state, where higher states indicated better outcomes. Baseline corresponded to last evaluable assessment before treatment administration.

Analysis population: Analysis was performed on Health status population which included participants who received at least one dose of the study drug and with an evaluable EQ-5D-5L at baseline and with at least one post-baseline evaluable EQ-5D-5L. Here 'Number analyzed' signifies participants with available data for each specified category.

Groups in this outcome

Cabazitaxel

Participants received Cabazitaxel 25 mg/m\^2 IV infusion for over 1 hour on Day 1 of each 3 week treatment cycle in combination with Prednisone 10 mg orally once daily and primary prophylactic G-CSF as per investigator decision, until radiographic disease progression, unacceptable toxicity, or participant's refusal of further study treatment (median duration = 22 weeks).

Abiraterone Acetate or Enzalutamide

Participants received either abiraterone acetate 1000 mg orally once daily from Day 1 to Day 21 of each 3 week treatment cycle in combination with prednisone 5 mg orally twice daily; or enzalutamide 160 mg orally once daily continuously from Day 1 to Day 21 of each 3 week treatment cycle, until radiographic disease progression, unacceptable toxicity, or participant's refusal of further study treatment (median duration = 12.5 weeks).
