Classification similarities. a Clustering of classification results using hierarchical clustering with Euclidean distance and average linkage. b The number of samples that were classified identically by the classifiers using Directed Cluster Analysis biomarkers (DCA), previously identified biomarkers (PI-CpGs), clinical variables (clinical), and the triple classifier (clinical + PI-CpGs + DCA). c, d The number of samples that were classified identically by the triple classifier and the Mayo Scoring System for the true outcome in c non-metastatic ccRCC at diagnosis and progress-free after 5 years (M0-PF) patients and d non-metastatic ccRCC at diagnosis with progression within 5 years (M0-P) patients
