CD84 and psoriatic arthritis: Finally, the Cox multivariate regression analysis confirmed the association between UTK survival and the TLR5 rs5744174-G (HR = 0.589; 95% CI = 0.37–0.92; p = 0.02), CD84 rs6427528-A (HR = 0.557; 95% CI = 0.35–0.88; p = 0.013) and PDE3A rs11045392 together with SLCO1C1 rs3794271-T (HR = 0.508; 95% CI = 0.32–0.79; p = 0.002) SNPs, adjusted for the psoriatic arthritis variable (Table 4).
