Replication of the association between rs6976 and DNA methylation at cg18099408. (AC) Plots show the association between genotype at rs6976 and the methylation levels at three CpGs measured by the pyrosequencing assay; (A) the discovery CpG cg18099408, (B) the CpG site located 5 bp downstream of cg18099408 and (C) the CpG site located 9 bp downstream of cg18099408. Data are shown for the 40 OA samples analysed. P-value was calculated using a Kruskal–Wallis test and was Bonferroni-corrected for multiple testing. Horizontal line represents the mean.
