Construction of the HCC prognostic risk model based on 9 m6A-related lncRNAs. (A and B) Least absolute shrinkage and selection operator (LASSO) regression was performed; the penalization coefficient λ in the LASSO model was tuned using 10-fold cross-validation and minimum criterion for the selection of m6A-related lncRNAs. (C) Barplot of the coefficients of selected lncRNAs. (D and G) Receiver operating characteristic (ROC) curves of risk model for predicting survival in the training (D) and validation cohort (G). (E and F) Distribution of risk score, survival status of HCC patients and heatmap of the 9 m6A-related lncRNAs in the high/low-risk group in the training (H) and validation (I) cohort.
