Identification of RAS-related prognostic genes. (a) Venn diagram showing the 14 intersection RAS-related prognostic genes. (b) The optimal number of clusters (K = 2) determined from cumulative distribution function (CDF) curves, and the classification effect is the best. (c) Heatmap of the expression of 14 RAS-related prognostic genes in the two clusters. (d) PCA confirming that osteosarcoma can be clearly separated into two clusters based on the expression of 14 RAS-related prognostic genes. (e) Kaplan–Meier curves for survival prediction of patients in the two clusters.
