CRP and rheumatoid arthritis: It was noticed that in RA patients with radiological involvement, the erythrocyte sedimentation rate (ESR) ((24 (2–120) vs. 14 (3–86); p < 0.001) and CRP ((0.9 (0.1–26.4) vs. 0.5 (0.1–16); p = 0.001) values were significantly higher than in RA patients without radiological involvement.
