Saliva is a reliable tissue for assaying OXTR methylation. DNA methylation values at OXTR cytosine-phosphate-guanine (CpG) site -934 are significantly correlated between (a) saliva and peripheral blood mononuclear cells (PBMC) (n = 142, r(140) = .78, p < .001), and (b) saliva and whole blood (n = 182, r(180) = .75, p < .001)
