Standardized beta and statistical significances obtained with a GLM model between the local graph metrics, namely degree (ki), betweenness centrality (Bi), clustering coefficient (Ci), and efficiency (Ei), measured from gray matter (GM) nodes of brain lobes of each hemispheres (left (L) and right (R)), 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)).
