The RA patients with various rs763110 genotypes did not significantly differ in DAS 28 score (5.84 [4.87-6.71] for CC, 6.23 [4.57-6.86] for CT, and 5.35 [4.88-5.88] for TT, P = 0.59, Kruskal-Wallis test) (Figure 3A) or TNF-α concentration (2.02 [1.21-3.08] for CC, 1.5 [1.19-1.9] for CT, and 1.76 [0.02-3.1] for TT, P = 0.24, Kruskal-Wallis test, values in pg/mL) (Figure 3B). This evidence concerns the gene TNF and rheumatoid arthritis.
