Fig. 3: Visualisation of 30 selected altered CpG islands analysis in the Discovery and TCGA-CHOL datasets.

a, b Discovery dataset (a) and TCGA-CHOL dataset (b) unsupervised hierarchical clustering analysis based on the average CGI β-values for the 30 BTC-specific altered CGIs. c ROC curves for the 11 CGIs showing an AUC ≥ 0.90 in the Discovery dataset. Red arrows indicate CGIs showing an AUC ≥ 0.90 also in TCGA-CHOL dataset.
