  • Office or automated BP is defined by either office or automated BP measurements exceeding the cutoff for normotension by the BP classification. Thresholds for hypertension by the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC7) are ≥123/82 mm Hg for office BP and ≥120/78 mm Hg for automated BP. Thresholds for hypertension by the American College of Cardiology/American Heart Association (ACC/AHA) are ≥119/79 mm Hg for office BP and ≥116/76 mm Hg by automated BP. 95% confidence intervals are shown in parentheses.
