Methylation in the promoter of <i>SLC6A4</i> at five CpG sites in high (grey) and low (white) work stress environments.

<p>Coordinates for each residue are 28 563 120 (CpG5), 28 563 109 (CpG4), 28 563 107 (CpG3), 28 563 102 (CpG2), and 28 563 090 (CpG1) as per GRCh37 build (NCBI Reference Sequence: NC_000017.10). Differences between work stress environments were significant as per t-test (p = 7.10E–06, p = 2.50E–05, p = 0.000292, p = 4.37E–06, and p = 0.000289 respectively). Standard errors are indicated.</p
