Table 3:
Number and frequency (%) of the best model for each white matter microstructural ROI in terms of variance explained. 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.
