Effect of the interaction of age and group differences in the degree of local and distant connectivity. Coordinates are based on MNI152 stereotactic space. Results reported in the table correspond to those clusters above 192 mm³ (three contiguous voxels).

Abbreviations: ADHD = children with attention‐deficit/hyperactivity disorder; ND = neurotypically developing children; TFCE = threshold‐free cluster enhancement.
