The prognostic value of the risk signature including 7 FIRLs in training set and validation set. A, B PCA (A) and t-SNE (B) analysis between high-risk and low-risk groups in training set. C, D Kaplan–Meier survival analysis (C) and AUC of ROC at 1-, 2- and 3-y OS (D) in training set. E, F Kaplan–Meier survival analysis (E) and AUC of ROC at 1-, 2- and 3-y OS (F) in validation set. G lncRNA expression patterns for patients in high/low risk groups based on the 7-FIRLs prognostic signature. H Comparison of OS prediction for different prognostic signatures. FIRLs ferroptosis and iron-metabolism related lncRNAs, AUC area under the curve, OS overall survival
