Table 3.

Effect sizes (Cohen’s d) comparing group differences on fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD). Group comparisons are the effect size of (1) the autism group (ASD) having increased diffusion compared to controls (HC), (2) the schizophrenia group (Sz) having increased diffusion compared to the autism group, and (3) the schizophrenia group having increased diffusion compared to controls. Negative effect sizes denote the effect in the opposite direction. Significant comparisons are in bold.
