Note: MDD = Major Depressive Disorder. rsubACC or lsubACC = Right or left subgenual anterior cingulate cortex. HSE = Hostile school environment. CD = Conduct disorder. ODD = Oppositional defiant disorder. All brain data were collected between Waves 3 and 4. Superscripts indicate significantly different means for a given measure.
