Blood pressure was measured repeatedly by using 3 methods: standardized research BP measurements at 6-month intervals; clinic BP measurements obtained during outpatient visits; and home BP measurements using a monitor that transmitted measurements electronically.  Patients provided 111 181 systolic BP (SBP) measurements (3218 research, 7121 clinic, and 100 842 home measurements) over 18 months. Systolic BP control rates at baseline (mean SBP <140 mm Hg for clinic or research measurement; <135 mm Hg for home measurement) varied substantially, with 28% classified as in control by clinic measurement, 47% by home measurement, and 68% by research measurement. Short-term variability was large and similar across all 3 methods of measurement, with a mean within-patient coefficient of variation of 10% (range, 1% to 24%). [Actualizado: 06 de septimbre 2013]
