Note: ANCOVAs were performed on total cerebellar gray and white matter volumes corrected for intracranial volume (ICV). Significant p-values (p < .05) are indicated in bold. PBD, youth with pediatric bipolar disorder; BD-OFF, offspring of subjects with bipolar disorder; HC, healthy controls; d, Cohen’s d.
