Standardized beta and statistical significances obtained with a GLM model between global graph metrics, namely density (D), assortativity (r), transitivity (T), modularity (Q), characteristic path length (CPL), and efficiency (Eg) measured in different brain networks (whole brain, inter-hemisphere, left and right hemispheres, different lobes, and subcortical regions), and the IQ scores (full scale intelligence quotient (FSIQ), verbal comprehension index (VCI), perceptual reasoning index (PRI), working memory index (WMI), and processing speed index (PSI)).
