Number of genes and probes in the three DNA methylation datasets Absher, Kirby and TCGA with different DNA methylation and gene expression statuses in PCa compared to normal tissue samples. The resemblance between the datasets is high in terms of: a probes with gain and loss of methylation, b genes with gain and loss of methylation and c genes classified in the groups UPUP, UPDOWN, DOWNUP and DOWNDOWN based on correspondence between methylation and gene expression. Red indicates the fraction of overlapping probes/genes, while grey indicates non-overlapping probes/genes
