Table 2:
Number and frequency (%) of the best model for each gray matter macrostructural ROI in terms of outcome variance captured (R2). Abbreviations: M0 = null model (i.e., covariates only); M1 = null model + sex; M2 = null model + gender; M3 = null model + sex + gender; M4 = null model + sex + gender + sex-by-gender interaction; ROI = regions of interest.
