Notes. L = left; R = right; Cau = caudate; GP = globus pallidus; Put = putamen; Tha = thalamus; Amy = amygdala; Hip = hippocampus.

*q = FDR-corrected significance level

^*p-value is below the FDR-corrected significance level

%SA = the percentage of surface area that significantly differs between ADHD and TD groups; p = p-value obtained from the statistical shape analysis pipeline with multiple comparison correction performed with age as a covariate; d = average Cohen's d effect size estimate for the magnitude of the diagnostic group difference at each vertex.
