Between-group comparisons for overweight (n = 13) versus healthy weight (n = 149) and substance using (n = 51) versus abstinent (n = 111) adolescents at baseline. For all contrasts, activated regions, number of contiguous voxels (k), Z values, and coordinates within the Montreal Neurological Institute (MNI) coordinate system are displayed. Peaks within the regions were considered significant at k ≥ 12, p < .05, whole brain corrected for multiple comparisons.
