Identification of a seven m6A-related lncRNAs prognostic signature. A LASSO coefficient profiles of the 29 m6A-related lncRNAs. B The penalization coefficient λ in the LASSO model was tuned using tenfold cross-validation and the minimum criterion. AUC metrics (y-axis) were plotted against log(λ) (bottom x-axis). The top x-axis indicates the number of predictors for the given log (λ). For the optimal λ, ten m6A-related lncRNAs with non-zero coefficient were selected. C K-M survival curve showed survival analysis of the seven m6A-related lncRNAs prognostic signature in TCGA-OV dataset. D ROC curve analysis of the seven m6A-related lncRNAs prognostic signature in TCGA-OV dataset
