| Change From Baseline to Weeks 4, 12 and EoT in Mean PR in the Tmax Window | Vital signs (blood pressure and pulse rate) were monitored using an ABPM device placed on the upper arm followed by intake of the double-blind study medication and worn for at least 24 hours. Tmax window of mirabegron and solifenacin was from 4-6 hours postdose. | Baseline and weeks 4, 12 and EoT (up to 12 weeks) | 
| Maximum 1-hour Change From Time-matched Baseline in SBP at Weeks 4, 12 and EoT | Vital signs (blood pressure and pulse rate) were monitored using an ABPM device placed on the upper arm followed by intake of the double-blind study medication and worn for at least 24 hours. The maximum 1 hour change from time-matched baseline was calculated as the maximum difference between the post-baseline hourly means and the time-matched baseline hourly means. | Baseline and weeks 4, 12 and EoT (up to 12 weeks) | 
| Maximum 1-hour Change From Time-matched Baseline in DBP at Weeks 4, 12 and EoT | Vital signs (blood pressure and pulse rate) were monitored using an ABPM device placed on the upper arm followed by intake of the double-blind study medication and worn for at least 24 hours. Tmax window of mirabegron and solifenacin was from 4-6 hours postdose. The maximum 1 hour change from time-matched baseline was calculated as the maximum difference between the post-baseline hourly means and the time-matched baseline hourly means. | Baseline and weeks 4, 12 and EoT (up to 12 weeks) | 
| Maximum 1-hour Change From Time-matched Baseline in PR at Weeks 4, 12 and EoT | Vital signs (blood pressure and pulse rate) were monitored using an ABPM device placed on the upper arm followed by intake of the double-blind study medication and worn for at least 24 hours. Tmax window of mirabegron and solifenacin was from 4-6 hours postdose. The maximum 1 hour change from time-matched baseline was calculated as the maximum difference between the post-baseline hourly means and the time-matched baseline hourly means. | Baseline and weeks 4, 12 and EoT (up to 12 weeks) | 
| Change From Baseline to Weeks 4, 12 and EoT in SBP Peak/Trough Difference | Vital signs (blood pressure and pulse rate) were monitored using an ABPM device placed on the upper arm followed by intake of the double-blind study medication and worn for at least 24 hours. Peak/trough difference was defined as the difference between the highest 1-h to lowest 1-h average per participant per visit. | Baseline and weeks 4, 12 and EoT (up to 12 weeks) | 
| Change From Baseline to Weeks 4, 12 and EoT in DBP Peak/Trough Difference | Vital signs (blood pressure and pulse rate) were monitored using an ABPM device placed on the upper arm followed by intake of the double-blind study medication and worn for at least 24 hours. Peak/trough difference was defined as the difference between the highest 1-h to lowest 1-h average per participant per visit. | Baseline and weeks 4, 12 and EoT (up to 12 weeks) | 
| Change From Baseline to Weeks 4, 12 and EoT in PR Peak/Trough Difference | Vital signs (blood pressure and pulse rate) were monitored using an ABPM device placed on the upper arm followed by intake of the double-blind study medication and worn for at least 24 hours. Peak/trough difference was defined as the difference between the highest 1-h to lowest 1-h average per participant per visit. | Baseline and weeks 4, 12 and EoT (up to 12 weeks) |
