For each DM, the predictor selection and coefficient estimates of the best model (boldface) and the second-best model with same number of predictors (plain face) are shown together with their significance level. The “Assessment” columns give the proportion of variance accounted for by the model and by which of the three applied regression criteria the model was favored. The “Validation” columns show the results of model validation within the sample and in a new sample of patients and controls. The confidence intervals (I.i-ii) were supposed to contain the 0 and 1, respectively, if the model held (for details, see text).

Cp = Mallows' Cp; AIC = Akaike's information criterion; Radj2 = adjusted R2; AntIns = anterior insula; TPol = temporal pole; ParOc = parieto-occipital.
