Results from multivariate logistic regression (Table 6) for ACR20, ACR50, and ACR70 response rates as dependent variables, and multivariate linear regression (Table 7) for DAS28-CRP, CDAI, SDAI, and morning stiffness as dependent variables, demonstrated no significant associations between demographic factors and clinical outcomes in RA patients. This evidence concerns the gene CRP and rheumatoid arthritis.
