Figure 2. WGCNA. (A) A Scale-free fit index as a function of soft-thresholding power. (B) The mean connectivity is a function of soft-thresholding powers. (C) Highly interconnected groups of genes were clustered and modules are represented by distinct colours in the horizontal bar. (D) Heatmap showed the correlations of module eigengenes with clinical traits. The numbers in each cell represent the correlation coefficients and P-value between clinical trait and module eigengenes.
