Unadjusted mean EPIC quality of life scores plotted over time for (A) urinary, (B) sexual, and (C) bowel quality of life. The SBRT patient scores are shown with a dashed line and the surgery patients are shown with a solid line. EPIC domain scores range from 0 to 100 with higher values indicating higher quality of life. For the sexual domain, the surgery scores are divided into those patients receiving the nerve-sparing (solid line) and non-nerve-sparing (dotted line) techniques. Asterisks (*) denote time points at which scores were clinically significantly different from baseline. Error bars denote 95% confidence intervals.
