In patients with craniopharyngioma (n = 70), mean/median baseline salivary oxytocin concentrations ranged between 0.32 pg/mL and 1.90 pg/mL for samples quantified using RIA (Brandi et al., 2020, Gebert et al., 2018, Hoffmann et al., 2017), and between 3.3 pg/mL and 3.6 pg/mL for samples quantified using EIA (Daubenbüchel et al., 2016, Özyurt et al., 2020). The gene discussed is OXT; the disease is craniopharyngioma.
