  1. Corrected p-value, location, atlas labels and major function of clusters with lower cortical thickness (CT) correlated with higher ScreenQ scores controlling for child sex and age, shown in Fig. 1A (thresholds: two-sided p-FDR < 0.10 and p-FDR < 0.05). Montreal Neurological Institute (MNI) coordinates are left–right, posterior-anterior and inferior-superior relative to the anterior commissure. Regions indicates the percentage of each cluster residing in the respective Desikan-Killiany DK40 atlas-defined area.
