Patients disposition. Abbreviations: AAP: abiraterone acetate plus prednisone; AE: adverse event; ITT: intent-to-treat and PD: progressive disease. ^*The 12 patients in the AAP group and the 2 in the placebo-AAP crossover group who were ongoing were included in the final analysis as those who could continue receiving treatment but discontinued treatment after data collection for final analysis. They are therefore regarded as those discontinued treatment (consent withdrawal) in the final analysis of overall population.
