Baseline Characteristics and Clinical Outcomes of Participants by Treatment Group^*

Baseline Characteristic	Anticholinergic Group (N=119)	Botox Group (N=112)
Age—years	57.2 ± 11.5	58.9 ± 10.7
Hispanic ethnicity—no. (%)†	19 (16)	21 (19)
Race—no. (%)†
White	92 (77)	88 (79)
Black	22 (19)	17 (15)
Other	5 (4)	7 (6)

Working outside the home—no. (%)	64 (54)	51 (46)
Prior anticholinergic therapy—no. (%)	67 (56)	66 (59)
Episodes of urgency incontinence—no./day‡	5.1 ± 2.8	4.9 ± 2.6
Health utility§	0.656 ± 0.03	0.667 ± 0.05

^*Plus-minus values are means ± SD. Except where noted, none of the baseline values differed significantly between the treatment groups.

^†Race and ethnic group were self-reported.

^‡Reported by patient in 3-day diary entries.

^§Utility scores are on a scale of 0 (death) to 1 (optimum health). P-value for difference in mean baseline utility score (QALYs) between groups is 0.03. Utility scores (QALYs) were calculated by obtaining baseline scores on the OABq, then applying the Yang et al. (2009)OAB-5D utility scoring methodology to estimate baseline utility values.
