  1. Age-adjusted mean cortical thicknesses for ROIs were obtained from FreeSurfer, and Cohen's d examined the difference between people with bipolar I (n = 40), bipolar II (n = 29) or bipolar spectrum disorder (n = 23) and controls (n = 49). Items of small- (d>0.2) or medium-effect size (d>0.5) are italicized. ant., anterior; BP1, bipolar I disorder; BP2, bipolar II disorder; BSD, bipolar spectrum disorder; CON, controls; pos., posterior.
