TABLE 4.

Comparison of the proportions of patients with clinically meaningful 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	% of patients with clinically meaningful reduction	P ^*	% of patients with clinically meaningful reduction	P ^*
Bowel	IMRT	73 (58.4%)	.01	27 (39.7%)	.02
Bowel	PBT	34 (39.5%)	.01	9 (19.1%)	.02
Urinary irritative/obstructive	IMRT	81 (65.8%)	.37	16 (22.9%)	.23
Urinary irritative/obstructive	PBT	48 (59.3%)	.37	6 (12.5%)	.23
Urinary incontinence	IMRT	37 (29.4%)	.88	17 (24.6%)	.83
Urinary incontinence	PBT	23 (27.4%)	.88	11 (21.6%)	.83

The value .01 is statistically significant; .02 is borderline statistically significant (in bold).

P‐values were derived from Fisher's exact test. P‐values reflect a test whether the difference in the proportion of patients experiencing clinically meaningful reduction is statistically significant between two modalities. P < .017 is considered significant to account for Bonferroni adjustment.
