Estimation, evaluation, and calibration in training set for the five m⁶A-related mRNAs risk prognostic model A, B Distribution of the risk score for the five m⁶A-related mRNAs in the risk model. B Dot plot of the different survival time patterns for each risk group. C The different expression of m⁶ A-related mRNAs in each patient are shown in the heatmap. D Kaplan–Meier analysis of CHOL patients indicated that patients in the low-risk group had better OS. E The 1-year (AUC = 0.928) and 2-year (AUC = 0.903) ROC curves show the superior accuracy prediction of five independent prognoses in the m⁶A-related mRNA model. F, G) Calibration curves for survival after 1 y (F) and 2 y (G using MRMRPM. CHOL: Cholangiocarcinoma; OS: overall survival; AUC: area under curve; ROC: receiver operating characteristics; MRMRPM; five m⁶A-related mRNAs risk prognostic model
