Difference in Gray Matter Volume in the 3 Clusters of Significant Volume Difference Between PBD and NPBD Subjects

	Peak Voxel MNI- Space (x y z)	P FWE- Corrected	T	Cluster Size (Voxels With P < .05)	Effect Size (Cohens d)
PBD < HC

Note: PBD, psychosis bipolar disorder; NPBD, no-psychosis bipolar disorder; HC, healthy controls; DLPFC, dorsolateral prefrontal cortex.
