Weight gene correlation network analysis (WGCNA) to obtain modules associated with periodontitis. (A) The soft threshold power in WGCNA was determined by analysis of network topology. (B) Clustering dendrogram of filtered genes (C) Heatmap showing the correlations between the gene modules and phenotypes. (D) Scatter plot of blue module correlation. (E) Venn diagram of the shared genes between the datasets of WGCNA-ERGs and DEGs.
