MIF and intestinal disorder: In addition, the IVW method findings indicated a significant association between colonic polyp and increased levels of cutaneous T cell-attracting chemokine (CTACK, Beta: 0.097, 95%CI: 0.003–0.190, p = 0.044) and macrophage migration inhibitory factor (MIF, Beta: −0.142, 95%CI: −0.236–0.048, p = 0.003), when considering the inflammatory circulatory cytokines as the outcome (Table 1; Supplementary Table S2).
