M_pt mean cortical thickness (in mm) in a given network for patients with remitted psychotic depression (n = 86), M_ct mean cortical thickness (in mm) in a given network for healthy controls (n = 159), SD standard deviation, β regression coefficient for patients with remitted psychotic depression versus healthy controls, SE standard error for regression coefficient, t value for testing against a mean difference of zero, p values and FDR-corrected p values are obtained from separate linear models run for each network, d effect size expressed as Cohen’s d.
