Table 4.

Results from regression analyses of Executive Function, cerebrovascular risk factors (CVRF), and vascular health. The values presented are regression coefficients standardized using the interquartile range. Step 1 = background characteristics; step 2 = background characteristics and CVRF; step 3 = background characteristics, CVRF, and intima medial thickness; step 4 = background characteristics, CVRF, and nitroglycerine-mediated dilation; step 5 = background characteristics, CVRF, and flow-mediated dilation; step 6 = background characteristics, CVRF, intima medial thickness, and flow-mediated dilation.
