The results of the pQTL analysis demonstrated that high levels of IL-7 in plasma are associated with a reduced risk of IPF (OR = 0.67, 95%CI: 0.47–0.97, P = 0.035), which is consistent with the findings of eQTL analysis (Supplementary material: Table S9). The gene discussed is IL7; the disease is idiopathic pulmonary fibrosis.
