Identification of immune cell-related prognostic genes characterized by a distinct microenvironment in hepatocellular carcinoma

Figure 1 Identification of immune-related differential genes by weighted gene coexpression network analysis in the The Cancer Genome Atlas database. A: Sample clustering analysis to detect outliers; B: Analysis of the scale-free fit index of the soft threshold power (β); C: The module merge threshold indicated by a horizontal line; D: Hierarchical cluster tree showing the results of modules in weighted gene coexpression network analysis; E: Heatmap analysis showing the associations between the module characteristic genes and immune cell infiltration.
