The change in trough clinic sitting systolic blood pressure measured at week 6 relative to baseline. The trough is the average of the non-missing values of 3 serial trough sitting systolic blood pressure measurements. Blood pressure was measured using a validated, automated device after the participant had been sitting for at least 5 minutes. Week 6 blood pressure was measured approximately 24 hours after the previous day's dose. An analysis of covariance (ANCOVA) model, with treatment group as a fixed effect and Baseline sitting clinic systolic blood pressure as a covariate was used for analysis.
The change in trough systolic blood pressure measured at final visit or week 8 relative to baseline. Ambulatory blood pressure monitoring measures blood pressure at regular intervals throughout the day and night. The trough is the average of all measurements recorded from 22 to 24 hours after dosing.
The change in trough systolic blood pressure measured at final visit or week 8 relative to baseline. Ambulatory blood pressure monitoring measures blood pressure at regular intervals throughout the day and night. The trough is the average of all measurements recorded from 22 to 24 hours after dosing.
The change in 24-hour mean systolic blood pressure measured at week 6 relative to baseline. Ambulatory blood pressure monitoring measures blood pressure at regular intervals throughout the day and night. The 24-hour mean is the average of all measurements recorded for 24 hours after dosing.
The change in mean trough clinic sitting systolic blood pressure measured at final visit or week 24 relative to baseline. Systolic blood pressure is the arithmetic mean of the 3 trough sitting systolic blood pressure measurements.
The change in 24-hour mean systolic blood pressure measured at week 24 relative to baseline. Ambulatory blood pressure monitoring measures blood pressure at regular intervals throughout the day and night. The 24-hour mean is the average of all measurements recorded for 24 hours after dosing.
The change in sitting clinic diastolic blood pressure measured at final visit or week 32 from Double-blind Baseline/Week 26. Diastolic blood pressure is the arithmetic mean of the 3 trough sitting diastolic blood pressure measurements. Each participant's blood pressure at the Final Visit/Week 26 of the open-label phase represented their Baseline blood pressure for the double-blind reversal phase.
The change in sitting clinic diastolic blood pressure measured at final visit or week 8 relative to baseline. Diastolic blood pressure is the arithmetic mean of the 3 trough sitting diastolic blood pressure measurements.
