Corrected micturition frequency was defined as the mean number of micturitions per 24 hours that participants had at end of treatment if their fluid intake had remained unchanged since baseline. Corrected micturition frequency was calculated as the baseline mean volume voided per micturition multiplied by the baseline mean number of micturitions per 24 hours divided by the mean volume voided per micturition at EoT.

The OAB-q is a self-reported questionnaire with items relating to symptom bother and health-related quality of life (HRQoL). The symptom bother portion consists of 8 items, rated on a 6-point Likert scale (1 through 6). The total symptom bother score was calculated from the 8 answers and then transformed to range from 0 (least severity) to 100 (worst severity). A negative change from baseline indicated an improvement.

The OAB-q is a self-reported questionnaire with items relating to symptom bother and HRQoL. The HRQoL portion consists of 25 HRQoL items comprising 4 HRQoL subscales (Coping, Concern, Sleep, and Social Interaction), each item was scored 1-6. The total score was calculated by adding the 4 HRQoL subscale scores and transforming to a scale from 0 to 100, with higher scores indicating better quality of life. A positive change from baseline indicated an improvement.

The PPBC is a validated, global assessment tool using a 6-point Likert scale on which participants rated their subjective impression of their current bladder condition. Participants assessed their bladder condition using this scale: 1. Does not cause me any problems at all; 2. Causes me some very minor problems; 3. Causes me some minor problems; 4. Causes me (some) moderate problems; 5. Causes me severe problems; 6. Causes me many severe problems.
