Fig. 1From: Number-needed-to-treat analysis of clinical progression in patients with metastatic castration-resistant prostate cancer in the STRIVE and TERRAIN trialsNNT for PFS, rPFS, and freedom from PSA progression comparing enzalutamide with bicalutamide. NNT for the STRIVE (a) and TERRAIN (b) trials at 1 and 2Â years. The lower limit of NNT for rPFS at 1Â year was not reported, as the rate difference between enzalutamide with bicalutamide covers the 0, and it is not meaningful to report a negative NNT value. NNT number needed to treat, PFS progression-free survival, PSA prostate-specific antigen, rPFS radiographic progression-free survivalBack to article page
