A significant positive correlation with age (p = 0.034) in the node betweenness in the left REC was found in the boys, whereas the girls showed no change with age (p = 0.602) (Figure 5C, left). The girls showed significant positive correlation with age (p = 0.010) in the node efficiency in the right REC, whereas the boys showed negative correlation with age (p = 0.162) (Figure 5C, right).
