Cortical thickness increment (in a degree of 2.5–5%) comparing autism spectrum disorder (ASD) children to age-matched typically developing (TD) children (P<0.01).

<p>Note-Data (C1, C2) are mean cortical thickness in mm.</p><p>**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).</p><p>*Indicates a significant difference with corrected P<0.05 after Bonferroni adjustment.</p><p>Δ2 Indicates percentage change between cortical thickness of ASD children (C2) and cortical thickness of TD children (C1), calculated as Δ2 = (C2–C1)/C1*100%.
