Compared with the remaining patients with RA, those with negative joint counts and normal CRP possessed a lower level of radiographic damage, were less frequently seropositive for rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibody (anti-CCP), and reported less usage of biologic disease-modifying antirheumatic drugs (bDMARDs) and glucocorticoids. Here, CRP is linked to rheumatoid arthritis.
