CRP and rheumatoid arthritis: To assess whether these inflammasomes and related proteins differed at different disease activity levels, the RA group was divided into high activity (DAS28-CRP > 5.1), moderate activity (3.2 < DAS28-CRP < 5.1), low activity (2.6 < DAS28-CRP < 3.2), and remission (DAS28-CRP < 2.6) groups according to DAS28-CRP [9].
