Fig. 2: Subgroup comparisons in the FEP sample.

Gray matter (A) and white matter (B) comparisons of subgroup SG1 (left) and SG2 (right) when compared to cases in the ‘None’ subgroup in the FEP sample. A Decreased gray matter volume was found in the FEP subgroup relative to the ‘None’ classification, including the caudate, whereas relatively increased gray matter was found in SG2 subcortical areas including the striatum. B Decreased white matter was also found in the SG1 subgroup in areas including the internal capsule.
