Outcomes

Primary Outcomes

Change From Baseline to 16 Weeks in Mean 24-hour Systolic Blood Pressure (SBP)

Mean 24-hour systolic blood pressure (SBP) was measured by using a 24-hour ambulatory blood pressure monitoring (ABPM) device attached to the participant's nondominant arm. Ambulatory blood pressure measurements were recorded every 20 minutes during the daytime (0700 to 2200 hours) and every 30 minutes during the nighttime hours (2200 to 0700), as preprogrammed into the device. For statistical analyses, diurnal hours were defined as 0800 to 2100 and nocturnal hours were defined as 0000 to 0600. Least Squares (LS) means were calculated using mixed model repeated measures (MMRM) adjusting for baseline, pooled sites, treatment, visit, treatment-by-visit interaction, and the stratified variable of diagnosis of hypertension.
