No significant differences in serum levels of visfatin and omentin were observed between the psoriasis patients and healthy controls (Figure 2, Supplementary Figure 22, Supplementary Figure 23, Visfatin: SMD = 0.43, 95% CI -0.25 to 1.10; Omentin: SMD = 0.89, 95% CI -1.53 to 3.31;). Here, ITLN1 is linked to psoriasis.
