TABLE 2.

Comparison of score changes at the end of RT and 3 months post‐RT between IMRT cohort and PBT cohort

EPIC‐26 domain	Radiation modality	End of RT		3‐months post RT
EPIC‐26 domain	Radiation modality	Mean change from baseline	P ^*	Mean change from baseline	P ^*
Bowel function	IMRT	−13.0	<.01	−9.3	.02
Bowel function	PBT	−6.7	<.01	−1.2	.02
Urinary irritative/obstructive	IMRT	−16.2	.98	−2.4	.03
	PBT	−16.4	.98	1.7	.03
Urinary incontinence	IMRT	−4.3	.23	−2.5	.21
Urinary incontinence	PBT	−2.6	.23	−0.4	.21

The value of <.01 represents statistical significance; the value of .02 represents borderline statistical significance (in bold).

P‐values were derived from Wilcoxon rank‐sum test. P ^‐values reflect a test whether score changes were different between two treatment cohorts. P < .017 is considered significant to account for Bonferroni correction.
