Correlations between the dose to the internal and external urinary sphincters and (A) urinary function, (B) urinary irritative/obstructive symptoms, (C) urinary bother, and (D) urinary urgency. Percentages indicate the portion of sphincter volume receiving the specified dose. The baseline EPIC score is referenced to 0 and identified as the vertical dashed line. The change in EPIC score is referenced from baseline. IUS, internal urinary sphincter; EUS, external urinary sphincter; CI, confidence interval.
