Table 1. Differences in longitudinal change in gray matter structure by group.

Regions with significant change in cortical thickness and surface area from 9 to 16 years of age for the children who remained in care as usual relative to children randomly assigned to foster care intervention as well as differences for children within the FCG who were randomly assigned before and after 24 months of age. L, left; R, right.
