Significant regional volume differences (P<0.01) comparing children with autism spectrum disorder (ASD) to age-matched typically developing (TD) children after supratentorial volume normalization.

Note-Data (V1, V2) are mean brain volumes after normalization to the supratentorial volume with a scale factor of 1000, no unit. **Calculated with two-sample t test to obtain original p-value (shown with P<0.01) between two groups, and with Bonferroni multiple region correction (x8 factor given 4 brain lobes in two hemispheres). *Indicates a significant difference with corrected P<0.05 after Bonferroni adjustment. Δ1 Indicates percentage change between volume of ASD children (V2) and volume of TD children (V1), calculated as Δ1 = (V2-V1)/V1*100%.
