The mean µ and standard deviation σ of the time difference in mean standardized residuals for mean FA are listed. The null hypothesis was tested at a significance level of $\alpha$ = 0.05, and significant findings are displayed in bold case. Hotelling’s $T^2$ statistics with 108 degrees of freedom, effect sizes (Cohen’s d), and statistical power are listed

BCC, body of the corpus callosum; CST, corticospinal tract; GCC, genu of the corpus callosum; ILF, inferior longitudinal fasciculus; IOFF, inferior occipitofrontal fasciculus; MdLF, middle longitudinal fasciculus; SCC, splenium of the corpus callosum; Sup-F, superficial frontal; Sup-P, superficial parietal; Sup-T, superficial temporal
