Change From Baseline in Mean Number of Protective Undergarments Changed Due to Urinary Leakage Per 24 Hours at Week 4 and 12	Baseline, Week 4, 12	Protective Undergarments included pads, protective padding, protective underwear (pull up), and briefs (diaper). The mean number of undergarments changed per 24 hours was calculated as the total number of undergarments changed divided by the total number of diary days collected at that visit. Change from baseline values were reported at week 4 for subsets of population with baseline values less than or equal to (=\<) 3.5 and more than (\>) 3.5 undergarments/day and at Week 12 for subsets of population with baseline values =\< 2.5 and \> 2.5 undergarments/day.
Percentage of Participants With Change From Screening in Patient Perception of Bladder Condition (PPBC) at Week 4 and 12	Screening, Week 4, 12	PPBC: a self-administered, single-item, questionnaire that asks participants to describe their perception of their bladder-related problems. The PPBC assessment is rated on a 6-point scale: 1=no problems at all, 2=some very minor problems, 3=some minor problems, 4=moderate problems, 5=severe problems, 6=many severe problems. Deterioration=score difference is greater than 0; no change=score difference is 0; minor improvement=score difference is -1; major difference=score difference is less than or equal to -2.
Overactive Bladder Questionnaire (OAB-q) Symptom Bother Score	Baseline	OAB-q: a self-administered, 33-item, questionnaire that assesses how much the participant has been bothered by selected bladder symptoms. Each item rated by participant on Likert scale 1 (least symptom bother) to 6 (most symptom bother). Symptom bother score derived as sum of scores for questions 1-8; lowest possible raw score: 8; highest possible score: 48. Data analyzed based on transformation of the score to a 0 to 100 scale \[(Actual total raw score - lowest possible value of raw score)/range\]\*100. Higher scores values indicative of greater symptom bother.

Each item rated by participant on Likert scale 1 (least symptom bother) to 6 (most symptom bother). Symptom bother score derived as sum of scores for questions 1-8; lowest possible raw score: 8; highest possible score: 48. Data analyzed based on transformation of the score to a 0 to 100 scale \[(Actual total raw score - lowest possible value of raw score)/range\]\*100.

Health Related Quality of Life (HRQL) Domain and Total Score of Overactive Bladder Questionnaire (OAB-q)	Baseline	OAB-q: self-administered, 33-item, questionnaire, assesses how much participant has been bothered by selected bladder symptoms. Each item rated on Likert scale 1 (least symptom bother) to 6 (most symptom bother). Questions 9 to 33 constitute HRQL, includes domains: concern, coping, sleep, and social function. HRQL domain and total raw score derived as sum of scores. Transformed score range 0 to 100 (Total HRQL or domain) = \[(Highest possible raw score-Actual total raw score)/Raw score range\]\*100. Higher transformed scores indicative of better HRQL.

Each item rated on Likert scale 1 (least symptom bother) to 6 (most symptom bother). Questions 9 to 33 constitute HRQL, includes domains: concern, coping, sleep, and social function. HRQL domain and total raw score derived as sum of scores. Transformed score range 0 to 100 (Total HRQL or domain) = \[(Highest possible raw score-Actual total raw score)/Raw score range\]\*100. Higher transformed scores indicative of better HRQL.
Overactive Bladder Satisfaction Questionnaire (OAB-S) Total Score on Satisfaction With OAB Control	Week 12	OAB-S: a validated self-administered instrument that evaluates OAB medication expectations, daily life with AB, and satisfaction with OAB medication and includes 3 stand-alone items that assess overall expectation, satisfaction, and willingness to continue treatment. Satisfaction coded on scale of 1 to 5: (1=very satisfied to 5=very dissatisfied). Coding reversed algorithmically and results transformed: total score range 0 to100. Higher final response value associated with better satisfaction.
Percentage of Participants With Overactive Bladder Satisfaction Questionnaire (OAB-S) Global Medication Satisfaction Question Response	Week 12	Participant's response to question, "overall, how satisfied are you with your OAB medication?" was obtained on a 5 point scale, 1- very satisfied, 2- somewhat satisfied, 3- neither dissatisfied nor satisfied, 4- somewhat dissatisfied and 5- very dissatisfied. Response values 1 and 2 were combined into "satisfied", and 4 and 5 were combined into "dissatisfied".
Mini Mental State Examination (MMSE)	Screening	MMSE measured general cognitive functioning: orientation, memory, attention, calculation, language, visuospatial functions. Total score derived from sub-scores; total ranges from 0 to 30, higher score indicates better cognitive state.
Change From Screening in Mini Mental State Examination (MMSE) Score at Week 12	Screening, Week 12	MMSE measured general cognitive functioning: orientation, memory, attention, calculation, language, visuospatial functions. Total score derived from sub-scores; total ranges from 0 to 30, higher score indicates better cognitive state. Change: mean score at Week X minus mean score at baseline
Change From Baseline in Post Void Residual (PVR) Volume at Week 4 and 12	Baseline, Week 4, 12	PVR volume is defined as volume of urine remaining in the bladder immediately after urination.
