Control<ADHD	-

Full results of the ‘control>ADHD’ comparison in the child groups including all ADHD subjects. The second section of the table provides the results of the same comparisons including only those patients with a history of pharmacological treatment with psychostimulant medication. Results are thresholded at p<0.05, MCTSB corrected for multiple comparisons. No clusters of thicker cortical mantle were observed in the ADHD sample compared to the control children (contrast ‘control<ADHD’).

^*Clusters in these regions also survive a threshold of p<0.001, MCTSB corrected for multiple comparisons.
