TNFAIP3 and rheumatoid arthritis: As shown in Table 2, we found a significant association between TNFAIP3 gene rs6920220 (AA vs. GA+GG: OR, 1.36; 95% CI, 1.24–1.50, P < 0.001, Figure 2), rs2230926 (TG+GG vs. TT: OR, 1.39; 95% CI, 1.11–1.72, P = 0.003, Figure 3), and rs5029937 (T vs. G: OR, 1.42; 95% CI, 1.17–1.73, P < 0.001, Figure 4) polymorphisms with the increased risk of RA.
