ESR or CRP, which inflammatory measure can accurately replace clinical measures in rheumatoid arthritis?

Our study emphasizes the fact that CRP is a better measure of inflammation than ESR and represents the information on the inflammatory component provided by both TJC and SJC, as appreciated by the close overlap. The CRP can replace the clinical measures (joint counts and Pain scale) more effectively than ESR, provided other causes for elevation of CRP are excluded.
