Note. APOE, apolipoprotein E; BIM, Brain in Motion; BIN1, bridging integrator 1; CLU, clusterin; CR1, complement receptor 1; CVC, cerebrovascular conductance (cm·s−1/mmHg); NAART, North American Adult Reading Test; PICALM, phosphatidylinositol-binding clathrin assembly protein; , maximum peak systolic blood flow velocity (cm·s−1/mmHg). aThe Pratt index describes the contribution of each independent variable to the variance in the dependent variable rounded to the nearest tenth. bCoefficient of multiple determination: R2 = 0.364; F(11,214) = 11.120; p < 0.001. cCoefficient of multiple determination: R2 = 0.355; F(11,214) = 10.702; p < 0.001.
