a Hierarchical clustering of module hub genes in the clustering analysis. Branches of the dendrogram group together with hub genes that are positively correlated. b Heatmap plot of the adjacencies in the hub gene network. The trait weight was included. Each column and row corresponds to one module hub gene (labeled by color) or weight. In the heatmap, red represents high adjacency (positive correlation) and blue represents low adjacency (negative correlation). Red squares along the diagonal are the meta-modules
