NCT ID: NCT02710071

Last Updated: 2020-10-19

Results Overview

24-h Systolic Blood Pressure is the average of all 24-h Ambulatory Systolic Blood Pressure recordings. The Wake Period Systolic Blood Pressure is the average of all Systolic Blood Pressures recorded every 15 minutes during the wake period. The Sleep Period Systolic Blood pressure is the average of all Systolic Blood Pressures recorded every 30 minutes during the sleep period. 24-h Diastolic Blood Pressure is the average of all 24-h Ambulatory Diastolic Blood Pressure recordings. The Wake Period Diastolic Blood Pressure is the average of all Diastolic Blood Pressures recorded every 15 minutes during the wake period. The Sleep Period Diastolic Blood pressure is the average of all Diastolic Blood Pressures recorded every 30 minutes during the sleep period.

PRIMARY outcome

Timeframe: At the end of 2 weeks of placebo therapy, at the end of 6 weeks of Nebivolol therapy and at the end of 6 weeks of hydrochlorothiazide therapy.

Population: The overall Number of Analyzed Participants for primary outcome (27) differs from the Overall Number of Placebo (baseline) Participants (41) because 14 participants were excluded from the analysis due to either low quality of acquired data or due to missing data. Data Analysis was performed for the same 27 participants and for the each test period.

24-h Systolic Blood Pressure is the average of all 24-h Ambulatory Systolic Blood Pressure recordings. The Wake Period Systolic Blood Pressure is the average of all Systolic Blood Pressures recorded every 15 minutes during the wake period. The Sleep Period Systolic Blood pressure is the average of all Systolic Blood Pressures recorded every 30 minutes during the sleep period. 24-h Diastolic Blood Pressure is the average of all 24-h Ambulatory Diastolic Blood Pressure recordings. The Wake Period Diastolic Blood Pressure is the average of all Diastolic Blood Pressures recorded every 15 minutes during the wake period. The Sleep Period Diastolic Blood pressure is the average of all Diastolic Blood Pressures recorded every 30 minutes during the sleep period.
