DAS28 (disease activity score 28)-CRP-3 (C reactive protein) score
Time Frame: Index plus or minus 1 month
|
The DAS-28 CRP-3 is a measure of disease activity in rheumatoid arthritis (RA) that assesses 28 joints in RA commonly affected.
The DAS-28 CRP 3 takes into account tender and swollen joint counts and CRP level (measure of inflammation in the blood).
The DAS-28 CRP 3 measure does not include patient global assessment of health.
