Volumes (in cc) of the clusters of significant gray matter differences (less than 1 false-positive cluster expected) across the three groups of patients at ANCOVA (omnibus test) and at the three post-hoc tests.
Localization is according to Tzourio-Mazoyer, et al. [24].
Structures involved for less than 0.5 cc are not listed.
NV: Normal Volunteers.
NonResp-SC: Non-Responder schizophrenia patients.
Resp-SC: Responder schizophrenia patients.
