Blood pressure variables: hSBP = home systolic blood pressure; hDBP = home diastolic blood pressure; hPP = home pulse pressure. CES-D = Centre for Epidemiological Studies-Depression Scale. Gender, MAQ, a hypertensive diagnosis, and high cholesterol were initially entered in the first block but did not significantly predict any cognitive factor and were removed from final analyses. For Speed/Executive Function analyses, ethnicity and CES-D scores were also entered after block one but were non-significant predictors and removed from final analyses.

^a Significant ΔR² are identified as follows: *p < .05, ** p < .01, + p < .001.
