Change From Baseline to Final Visit in the Mean Number of Micturitions Per 24 Hours
A micturition is any voluntary urination (excluding incontinence only episodes). The mean number of micturitions per 24 hours were calculated from the data recorded by the participant during the 3-day micturition diary period.
Time frame: Baseline and final visit (up to Week 12)

A treatment-emergent adverse event (TEAE) was defined as an adverse event (AE; defined as any untoward medical occurrence in a patient administered a study drug) that started or worsened in the period from the first double-blind medication intake until 30 days after the last double-blind medication intake. The following TEAEs were selected for inclusion in the analysis: Dry mouth (aptyalism, dry mouth, dry throat), constipation (constipation), blurred vision (vision blurred, myopia, refraction disorder, accommodation disorder).
Time frame: From first dose of study drug up to 30 days after last dose of study drug (up to 16 weeks)
