Percentage of promoter methylation (Met%) in UCWBC DNA samples and relative expression ratio (RER) in FPT RNA samples of all six candiate genes*.

Note: *Overall Met% is the percentage of methylated cytosine in the CGI(s) (regions mark as BSPCR in Fig 2) was determined by bisulfite sequencing; levels of gene expression normalized to β-actin level as a ratio using values of transcripts in FPT samples matched to UCWBC samples (n = 14) determined by real time RT-PCR.
