Comparative analysis of the effectiveness of abiraterone before and after docetaxel in patients with metastatic castration-resistant prostate cancer

Figure 4 Radiographic progression-free survival of abiraterone with prednisone vs placebo with prednisone. Hazard ratio (HR) associated with abiraterone with prednisone vs placebo with prednisone for Radiographic-PFS were calculated using random effect model. The HR and 95%CI for each trial and the final combined results are demonstrated numerically on the left and graphically as a forest plot on the right. For individual trials: filled in square, hazard ratio; lines, 95%CI; diamond plot, overall results of the included trials. PFS: Progression-free survival.
