          PCP = primary care provider. *Diabetic patients presenting for a primary care visit to 1 of 92 participating providers were referred for eligibility assessment if their lowest triage blood pressure was ≥140/90 mm Hg. *Number of responses varied by individual item.

            Each curve is shown with the other 2 blood pressure components adjusted to their mean value and the intensification rate for the average provider and clinic site. For each blood pressure component, the curve is presented only for a range of values actually seen when the other 2 components are both close to their mean (±10 mm Hg of the mean value).
