Qualifying BP was defined as the highest 2 of the last 3 office BP readings taken in an outpatient office visit. Baseline BP was the mean of at least 12 BP readings taken over a 1-week period at home. Maintenance BP was defined as the last home BP reading transmitted while still in the program. DBP indicates diastolic blood pressure; SBP, systolic blood pressure.
aP < .001 compared to baseline and qualifying values.
