Fig. 2: Effect size estimates (Cohen´s d) for differences in cortical thickness between obese versus normal weight subjects in direct comparison with previously published effect size estimates for cortical thickness results in major depression (MDD) and bipolar disorder (BD).

a Plot depicting the positive correlation between effect size estimates for thickness results in all cortical regions mapped to the respective lobe between obesity and MDD (r = 0.452) and b between obesity and BD (r = 0.513). c Bar diagram displaying effect size estimates for cortical thickness results separately for all cortical regions.
