Figure 3. Identification of key genes that can predict the 5-year survival time of breast cancer patients. (A) Random forest screening for the top 10 genes with a high Gini coefficient of average decline. (B) Expression of the 10 selected genes in samples with a survival time of more than or less than 5 years. (C) Kaplan-Meier analysis of overall survival for the signatures associated with expression of the 10 genes in breast cancer. (D) AUC of the 10 selected genes that affect the survival time of breast cancer.
