Figure 2. Identification of hub genes in gastric cancer using the WGCNA algorithm. (A) The soft threshold is determined by function. The left panel shows the relationship between the scale-free network evaluation metric R2 and the soft threshold, and the right panel shows the relationship between average connectivity and the soft threshold. (B) Dendrogram of gene clustering and different colored modules. (C) Gene clustering dendrogram obtained by merging similar modules. (D) Correlations between merged modules and clinical traits, correlation coefficients and p-values are shown in the corresponding modules of different colors. (E) Scatterplot of MM and GS in the black module.
