Construction of WGCNA to identify DE-CMG modules in the GSE33463 dataset. A Cluster dendrogram of module eigengenes to detect outlier samples. B Dendrogram of all expressed genes in the PAH and control samples clustered based on a dissimilarity measure (1‐TOM). C Analysis of the scale-free topology fit index and the mean connectivity for various soft-threshold powers (β) for the genes. D Hierarchical clustering tree based on the topological overlap dissimilarity (1-TOM). E Heatmap of the module-trait relationships. The corresponding P values are also annotated
