Prostate cancer–specific survival for the 3-year landmark analysis of the Radiation Therapy and Oncology Group 92-02 trial. Patients in the control arm were treated with short-term androgen deprivation and radiation therapy; patients in the experimental arm were treated with long-term androgen deprivation and radiation therapy. Gray's test statistic was used, and all statistical tests were two-sided. Error bars at 5, 8, and 10 years = 95% confidence intervals.
