Screening for immune characteristic genes. A A Venn diagram for the DEGs, the module-DEGs and the immune-related genes. B We selected the top 10 genes, sorted by average importance, using a SVM. Red implies a higher expression level and green represents a lower expression level. C We selected the top 10 genes, sorted by mean decrease accuracy, using a RF. Red refers to a higher expression level and green denotes a lower expression level. D, E The key genes for screening using the LASSO-Cox algorithm. F A Venn diagram for the genes that we selected using a SVM, RF, and LASSO-Cox algorithm
