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).

Note-Data (C1, C2) are mean cortical thickness in mm.
**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.
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%.
