Hierarchical clustering heatmap of differentially methylated probes. Centroid clustering was used as linkage criterion. Shown are all significantly differentially methylated probes between samples with fibrotic progression (FP) and those with stable disease (SD) at an FDR threshold of 0.1. Additional file 12: Table S3 contains the exact location of all 25 CpG sites. Additional file 3: Figure S3 shows the hierarchical clustering for training and test cohort separately.
