Survival analysis of LUAD based on risk group and risk plot. a, b: The figures showed that overall survival of high-risk group was significantly worse than low-risk group in the training set (a) and validation set (b); c, d Patients were divided into two risk groups by median value of the risk score in the training set (c) and validation set (d); e, f The distribution of patients with survival status based on two risk groups in the training set (e) and validation set (f); g, h The heatmap of the expression of 19 ferroptosis-related lncRNAs between two-risk group in the training set (g) and validation set (h)
