Mean Values for Executive Function, Frontoparietal rCBF, and Frontostriatal rCBF for Groups Above and Below the Means for SBP and Educational Level

	Education <15.4 Years: SBP <120.1 mm Hg, n=43	Education <15.4 Years: SBP >120.1 mm Hg, n=60	Education >15.4 Years: SBP <120.1 mm Hg, n=52	Education >15.4 Years: SBP >120.1 mm Hg, n=60
Executive function	−0.18	−0.87	0.42	0.65
Frontoparietal rCBF	10.7	−6.2	21.4	36.1
Frontostriatal rCBF	−27.8	−43.1	−21.9	1.2

Comparison of means showed that the group with lower educational level and higher SBP differed from all other groups for executive function (P≤0.02) and frontoparietal rCBF (P≤0.06). The group with lower educational level and higher SBP also differed from both higher education groups for the frontostriatal rCBF (P≤0.05). rCBF indicates regional cerebral blood flow; SBP, systolic blood pressure.
