CD160 and breast cancer: As shown in Supplementary Table S2, the methylation levels of CD160_CpG_2, CD160_CpG_3 and CD160_CpG_5 were inversely correlated with age in controls (Spearman rho = −0.191, −0.150 and −0.146, respectively), whereas methylation levels of CD160_CpG_3 were inversely correlated with age in BC cases (Spearman rho = −0.240).
