Fig. 1

The network structure based on 209 adolescents. The network structure is a network of EBICglasso based on GGM. Green edges represent positive correlations, and red edges indicate negative correlations. The thickness of the edge reflects the magnitude of the correlation. a The network is with “circle” layout for easy viewing. It is important to note that the node positions don’t indicate Euclidean distances. The value (weight) on the edge indicates regression coefficient after regularization. b The network is with MDS, showing proximities among variables as distances between points in a low-dimensional space
