Prognostic value of m⁶A methylation-related lncRNAs in PTC patients in the training cohort. (A) Forest map of univariate Cox regression analysis on relationship between differential expression of lncRNAs associated with methylation of m⁶A RNA and prognosis of PTC. (B) Three m6A RNA methylation-associated DELs were selected by the least absolute shrinkage and selection operator (LASSO) Cox models. (C) Cross-validation for tuning parameter selection in the LASSO model. (D) Heatmap and scatter plot of risk scores constructed from lncRNAs in the training cohort. (E) Kaplan-Meier survival curves of the high and low risk groups in the training cohort. (F) Receiver operating characteristic (ROC) curves for predicting 1, 3, and 5-year disease-free survival of PTC patients in the training cohort.
