The List of White Matter Tracts with Significant Difference in Edge Density Between the Children with ASD and TDC on Voxel-Wise TBSS Analysis

White matter tracts	No. of voxels
Body of corpus callosum	2,712
Splenium of corpus callosum	1,689
Left superior corona radiata	1,615
Right superior corona radiata	166
Left posterior corona radiata	435
Right posterior corona radiata	418
Left superior longitudinal fasciculus	1,243
Right sagittal stratum	8

Each cell represents the number of voxels with significantly lower edge density (p < 0.05) in children with ASD compared with TDC on voxel-wise TBSS analysis after correction for multiple comparison. There were no voxels with significantly higher edge density in children with ASD compared with TDC.

ASD, autism spectrum disorder; TBSS, tract-based spatial statistics; TDC, typically developing children.
