Table 3.

Contrast Comparisons of Cortical Thickness (CT) at 0, 12, 24, and 36 Months, Based on CT Point Slope Estimates From Growth Curve Models Reported in Table 2.

Note: ES = effect size; IFG, inferior frontal gyrus; oper = pars opercularis; orb = pars orbitalis.

B estimates represent group difference in CT, where group was coded as healthy control = 0 and bulimia nervosa = 1.

ESs were calculated as the (Mean_{CT BN} – Mean_{CT HC})/residual standard deviation.⁴⁹
