CRP and rheumatoid arthritis: This variant was inversely correlated with RA disease activity measures such as 66SJC (rho = −0.54, CI: −0.7840 to −0.1520, P = 0.008), 68TJC (rho = −0.47, CI: −0.7461 to −0.06169, P = 0.023), 28TJC (rho = −0.44, CI: −0.7271 to −0.02019, P = 0.036), 28SJC (rho = −0.51, CI: −0.7651 to −0.1055, P = 0.014) and DAS28-CRP (rho = −0.6, CI: −0.8247 to −0.2166, P = 0.004) (Fig. 4A).
