For each tract investigated, the percentage of the tract that passed the FDR threshold is given (FDR threshold for IHTT-slow vs control FA = 0.0038, for MD = 0.0036, and for IHTT-normal vs control FA = 6.5 × 10−4), as well as the minimum p value for group differences on each tract. pocg, Postcentral gyrus; prcg, precentral gyrus.
