Correlations between methylation levels for the three genes. A significant correlation was observed between percentage of methylated reference (PMR) values for adenomatous polyposis coli (APC) and ras association domain family protein 1A (RASSF1A) (C) and between PMR values for RASSF1A and oestrogen receptor 1 (ESR1) (B). No clear correlation was observed between PMR values for APC and ESR1 (A).
