2.3. 24 h Ambulatory Blood Pressure Monitoring
pain
The monitoring of 24 h ambulatory blood pressure was conducted using ambulatory blood pressure monitors (Spacelabs Medical, Ebeltoft, Denmark). The monitors were calibrated to measure blood pressure with a half-hour span between 7:00 AM and 11:00 PM, and with an hour span between 11:00 PM and 7:00 AM Participants recorded wake-up and bed times. Using this information, computer software (Sentinel, Ebeltoft, Denmark, version 11.5.2.13260) calculated systolic and diastolic blood pressure measurements for the entire monitoring period, as well as separately for the sleeping and waking periods. One participant who completed the trial did not complete the blood pressure monitoring due to experiencing pain during the measurements.
