CRP and rheumatoid arthritis: When significant, the reductions were around 70% in the overall analysis, and reached 80% in the more severe stratum, both from logistic regression models; from linear models, the significant beta coefficients were in the order of −0.70 for the DAS28-CRP and −3.6 for the SDAI and increased by 1.5 (reaching about −1.10 and −5.30) in the two strata of long-standing and more severe RA, respectively.
