CXCL6 and dysplasia: Eight of the 33 immune‐related markers (IL‐33, BCA‐1, GRO, CCL19 (MIP‐3B), sTNFRII, CXCL6 (GCP2), CRP and MIP‐1B) were inversely associated with dysplasia, with univariate ORs ranging from 0.30 (95%CI: 0.12–0.77) for IL‐33 to 0.76 (95%CI: 0.59–0.99) for MIP‐1B (Figure 2; Table S4).
