Functional analyses of high- and low-risk key genes. a In the effect size (log₂FC)—log₁0 (FDR) volcano map, the red triangle, and green triangle represent significantly upregulated and down-regulated DEGs, respectively, the horizontal dotted line represents FDR < 0.05, the two vertical dotted lines represent |log₂FC|> 1, and the point size represents the absolute value of log₂FC. The larger the value, the larger the point; b Based on the high- and low-risk groups, the changes in DEGs with the corresponding diagnostic scores from a low to a high expression level. c The horizontal axis represents the number of genes, the vertical axis represents the name of the item, and the color and size of the point represent the significant FDR value. The closer the color of the point is to red, the greater the color and the greater the significance. DEGs, differentially expressed genes; DERs, differentially expressed RNAs; FDR, false discovery rate
