When remission of RA from baseline to year 1 was assessed using different measures (the DAS28-CRP, the Clinical Disease Activity Index [CDAI] [26], and the Simplified Disease Activity Index [SDAI] [27]), the proportions of patients achieving disease remission were similar in the SC abatacept and SC adalimumab treatment groups (with the DAS28-CRP, 43.3% [95% CI 37.4%, 49.1%] versus 41.9% [95% CI 36.0%, 47.9%]; with the CDAI, 23.5% [95% CI 18.5%, 28.5%] versus 24.0% [95% CI 18.8%, 29.1%]; and with the SDAI, 23.3% [95% CI 18.3%, 28.3%] versus 24.8% [95% CI 19.6%, 30.0%]). Here, CRP is linked to rheumatoid arthritis.
