Regions with group by sex interaction in axial diffusivity. Clusters (Table 2) showing a significant (TFCE p < 0.05) group by sex interaction effect in measures of axial diffusivity are highlighted. In total, six clusters incorporated areas of the body, genu, and splenium of the corpus collosum as well as areas of the right corona radiata and external capsule. Within these regions, ASD males showed decreased AD compared to TD males while ASD females showed increased AD compared to TD females (Fig. 7). Images are presented in R/L radiological convention with MNI z coordinates in millimeters. Skeletonized statistical overlays have been “inflated” for display
