Partial correlations (r) were calculated between the proportions of gray or white matter of regions identified in VBM analyses and cognitive scores including executive function, memory, and Trails A scores with vocabulary included as a covariate. Significant correlations (P < 0.05) are presented that include all participants (ALL) and only those participants that do not report hypertension (HT−). R: right hemisphere; L: left hemisphere.
