Table 4 Urogenital distress inventory-6 and incontinence impact questionnaire-7 score comparisons (mean points ± SD)

	UDI-6 preop	UDI-6 postop	IIQ-7 preop	IIQ-7 postop
Burch (n = 22)	78.22 ± 20.45	49.81 ± 33.71	64.87 ± 31.68	48.92 ± 36.33
Control (n = 26 UDI-6 n = 25 IIQ-7)1	67.95 ± 27.91	63.94 ± 28.67	64.11 ± 26.95	55.79 ± 34.68

¹One participant in control cohort with incomplete preop IIQ-7, therefore used only for UDI-6 data. UDI-6: Urogenital distress inventory-6; IIQ-7: Incontinence impact questionnaire-7.
