Ferroptosis biomarkers predict tumor mutation burden's impact on prognosis in HER2-positive breast cancer

Figure 3 Prognostic analysis of four ferroptosis-related gene signature models in the TCGA cohort. A: The optimal lambda resulted in nine nonzero coefficients; B: The partial likelihood deviation curve was plotted vs lambda; C: Risk curves were plotted in the TCGA cohort; D: Kaplan–Meier curves for the overall survival of patients in the high-risk and low-risk groups in the TCGA cohort; E: The area under the curves of time-dependent receiver operating characteristic curves verified the prognostic performance of the risk score in the TCGA cohort; F: T-SNE analysis of the TCGA cohort. OS: Overall survival.
