Figure 2. — Association of mean CBF with DBP and SBP. (a) CBF is correlated with DBP (β = −0.13, P = 0.048, R² = 0.13) but not with SBP (β = −0.07, P = 0.275, R² = 0.12), after controlling for the selected covariates (sex, age, race, cognitive status, diabetes, smoking, alcohol use, heart failure, and cholesterol). (b) The relative importance of each variable is normalized to sum 100% of the explained portion of the total variance of the CBF. Abbreviations: CBF, cerebral blood flow; DBP, diastolic blood pressure; SBP, systolic blood pressure.
