Remission rates by different criteria in different Disease Activity Score28 (DAS28) score-based statuses.
| Remission status | Odds Ratioa | Non-remission status | |
|---|---|---|---|
| Fulfillment of modified ARA remissionb | |||
| DAS28-ESR (<2.6) | 36.99% (64/173) | Reference | 0.45% (3/662) |
| DAS28-MCP-1 (<2.2) | 75.61% (62/82) | 5.28 | 0.80% (6/753) |
| DAS28-CRP (<2.5) | 70.00% (49/70) | 3.97 | 2.35% (18/765) |
| SDAI (≦3.3) | 54.10% (66/122) | 2.01 | 0.14% (1/713) |
| Fulfillment of 2011 ACR/EULAR remission definitionc | |||
| DAS28-ESR (<2.6) | 49.13% (85/173) | Reference | 2.27% (15/662) |
| DAS28-MCP-1 (<2.2) | 81.71% (67/82) | 4.62 | 3.98% (30/753) |

The remission status (corresponds to positive predictive values in Tables 5 and 6) of patients with rheumatoid arthritis was classified by indicated cut-offs and percentages calculated in each category. Abbreviations were the same as in Table 1. aAll odds ratios vs. the reference in each category gave P < 0.005. bSatisfied the modified American Rheumatism Association (ARA) remission criteria during 835 visits (ref. 5). Inside parentheses are visit numbers. DAS28-MCP-1 vs. SDAI: P = 0.002 (95% C.I.: 1.42–4.88); DAS28-MCP-1 vs. DAS28-CRP: P = 0.438 (95% C.I.: 0.65–2.72). cAmerican College of Rheumatology/European League against Rheumatism (ACR/EULAR): as in ref. 23. DAS28-MCP-1 vs. DAS28-CRP and SDAI rendered both P > 0.500.
