Correlation¹ between FA values and Brain Volumetric variables from the voxelwise ROIs.

<p>Note - Values are Pearson Correlation coefficients; *statistical significance at level <0.05 (*) and <0.01 (**); CN = Cognitively Normal; MCI = Mild Cognitive Impairment; AD = Alzheimer Dementia; NA = not assessed because WM tract was not statistical significant; R = right; L = left; IFOF = inferior fronto-occipito fasciculus; ILF = Inferior longitudinal fasciculus; SLF = superior longitudinal fasciculus.</p>1<p>FA values extracted from voxelwise region of interests (ROIs); for MCI the ROI from the contrast MCI versus controls (controlled for age and gender); for AD the ROI from the contrast AD versus control (controlled for gender, age and gray matter).</p>2<p>Volume in mm^3.
