Bowel function. (a) EPIC bowel summary domain scores at baseline and following SBRT for prostate cancer. (b) EPIC bowel summary domain scores in patients with or without urinary symptom flare. Thresholds for clinically significant changes in scores (½ standard deviation above and below the baseline) are marked with dashed lines. EPIC scores range from 0–100 with higher values representing a more favorable health-related QOL.
