The 7-RNA signature-related risk score and OS prediction of WT Bf-CM patients. KM analysis reveal the OS differences between high and low risk groups and ROC curves assess the predictive performance of the signature-related score in training set (a); in testing set (b) and in the entire set (c). P values were calculated by two-sided log-rank tests, total AUC values were estimated and 95% CI were computed with 2000 stratified bootstrap replicates. d Risk-related plots illustrate the risk scores, survival status of patients and heatmap of 7 RNAs’ expression
