Figure 1From: Clinical disease activity and acute phase reactant levels are discordant among patients with active rheumatoid arthritis: acute phase reactant levels contribute separately to predicting outcome at one yearDistribution of acute phase reactant levels at baseline. Distribution of ESR and CRP levels at baseline (A) among the 9,135 patients who had a visit with active RA (CDAI >2.8), and (B) among the 4,031 biologic-naïve patients who had a visit with active RA (CDAI >2.8). CDAI, Clinical Disease Activity Index; CRP, C-reactive protein; ESR, erythrocyte sedimentation rate; RA, rheumatoid arthritis.Back to article page
