Changes in mean systolic and diastolic blood pressure over follow-up

Blood pressure	Baseline	6 months	p	12 months	p
Systolic BP	171 ± 26	142 ± 18	<.0001	141 ± 17	<.0001
Diastolic BP	89 ± 14	78 ± 10	<.0001	80 ± 9	<.0001
Hypertension cure (%)^a		4.9%		5.7%
Hypertension improvement (%)^b		77.4%		70.8%
Pulse pressure (mmHg)	85.02 ± 22.08	63.36 ± 16.15	<0.001^c	61.34 ± 14.42	<0.001^c

^aCure = diastolic blood pressure ≤90 mmHg and systolic blood pressure ≤140 mmHg, off antihypertensive medications

^bImprovement = diastolic blood pressure ≤90 mmHg and/or systolic blood pressure ≤140 mmHg on the same or reduced number of medications or a reduction in diastolic blood pressure by at least 15 mmHg with the same or a reduced number of medications
