Key module identification based on WGCNA. (A) Identification of outlier samples in GSE24030. (B) Scale-free fit index analysis and average connectivity for soft-thresholding power from 1 to 20. (C) Dendrogram of the WGCNA network, with each color representing a different module. (D) Correlation heatmap of module feature vector. (E) Heatmap showing the correlation between module and clinical characteristics. (F) Scatter plot of gene significance (GS) versus module membership (MM) in the yellow module
