Correlation between Ferroptosis-Related Gene Signature and Immune Landscape, Prognosis in Breast Cancer

Figure 4

Construction of the prognostic prediction model and model validation. (a, d, g) Risk score (top), disease-free survival (middle) of the patients, and expression profiles of the six ferroptosis-related genes (bottom) in TCGA training, TCGA internal validation, and GSE21653 external validation sets. (b, e, h) The areas under the curve of the time-dependent ROC curves show and verified the prognostic performance of the risk scores in TCGA training, TCGA internal validation, and GSE21653 external validation sets. (c, f, i) Kaplan–Meier curves for disease-free survival in the high- and low-risk groups in TCGA training, TCGA internal validation, and GSE21653 external validation sets.
