Logistic regression model exploring association between baseline anti-CCP titer and radiographic and functional outcome at 5 years
| 5-year outcome | OR (95% CI) | P | Adjusted ORa | Adjusted Pa |
|---|---|---|---|---|
| Erosions | 1.03 (1.02, 1.04) | < 0.0001 | 1.03 (1.01, 1.03) | < 0.0001 |
| Larsen score > 15 | 1.03 (1.02, 1.03) | < 0.0001 | 1.02 (1.01, 1.03) | < 0.0001 |
| HAQ ≥ 1 | 1.01 (1.01, 1.02) | < 0.0001 | 1.00 (0.99, 1.01) | 0.47 |
aAdjusted for age, gender, symptom duration and CRP, RF, HAQ, and swollen- and tender-joint counts at baseline. OR, odds ratio; CI, confidence interval. Baseline anti-CCP titer was available in 596 patients. ACR, American College of Rheumatology criteria for rheumatoid arthritis; DAS, disease activity score; HAQ, Health Assessment Questionnaire.
