Comparison of summary criteria for the most commonly reported overactive bladder health-related quality of life instruments

	OAB-q (n = 34 studies)	KHQ (n = 18 studies)	PPBC (n = 12 studies)
Comprehensively considers a wide variety of OAB symptoms and bother	Yes	Yes	No, global score only
Is specific to OAB	Yes	No, developed for lower urinary tract syndrome generally	Yes
Has MID data available	Yes	Yes	Yes
Can be used to generate a utility value	Yes	Yes	No; algorithm not available

All individual treatment arms within studies are included as a separate row. The overall HRQoL and symptom bother scale are included as separate columns. The four subscales (coping, concern, sleep, social) of the overall HRQoL are also included as separate columns. The range of OAB-Q score is 0–100 (where a higher symptom bother score indicates greater symptom bother, while lower HRQoL scores indicate greater impact on QOL)
