Figure 5. Analysis of immune cell infiltration and module gene identification. (A) Violin plot depicting the distribution of 24 immune cell types; significant differences between control and SCM groups are noted in red. (B) Heatmap of correlations between the 24 immune cells, with color coding indicating the nature of the correlation. (C) WGCNA-derived co-expression modules, displayed in a color-coded gene dendrogram. (D) Module-trait relationship grid, where each cell shows the correlation coefficient and P-value, with color indicating the direction of the correlation.
