All data were visually inspected for major artifacts before being included in analyses. Cingulum data was available for 54 participants. Using IBM SPSS version 20, ANCOVA and partial correlational analyses were conducted with mean FA values of all tracts, along with clinical and neuropsychological variables. Age and depressive symptoms were controlled for in these analyses, as these factors have been known to influence white matter integrity (10, 36–38). A threshold of p<.05, two-tailed, was used to define statistical significance.
