^*Significant at the .05 level, 2-sided test after correction for false discovery rate (FDR)

¹Associations reported for symptoms of inattention and impulsivity are based on linear regression controlling for age, gender, total brain volume, and TR.

²Regions from analysis of group differences in cortical thickness presented in Tables 2–3, with region 1 having the most pronounced thickness difference as a function of institutionalization, region 2 having the second most pronounced thickness difference, and so on.
