Identification of a Two-m6A RNA Methylation Regulator Risk Signature as an Independent Prognostic Biomarker in Papillary Renal Cell Carcinoma by Bioinformatic Analysis

Figure 4

Risk signature of pRCC with two m6A RNA methylation regulators. (a) The screening process of m6A RNA methylation regulators involved in later LASSO regression by univariate Cox regression. There were 3 m6A RNA methylation regulators screened out. (b, c) The coefficients and variable selection using the LASSO model. Two m6A RNA methylation regulators were selected to build the risk score model as a risk signature. (d) Kaplan-Meier OS curves for patients in the high- and low-risk groups based on the risk score. pRCC: papillary renal cell carcinoma; LASSO: least absolute shrinkage and selection operator; OS: overall survival.
