Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary clinical outcomes [1-3]: [1] Intensity of RA symptoms and signs (0-400) by patient self-rating, sum of four visual analogue scales (each 0-100): joint inflammation in past 3 months, joint swelling today, joint pain today, joint stiffness today. Measurement time points: every 3 month between months 0 and 48. Primary analysis: Area Under the Curve according to trapezoidal rule: Change from months 0-3-6-9 to months 39-42-45-48; [2] C-Reactive Protein in serum. Measurement time points: every 3 month between months 0 and 48. Primary analysis: Area under the Curve according to trapezoidal rule: Change from months 0-3-6-9 to months 39-42-45-48; [3] Radiological signs of joint destruction in hands and feet: Ratingen-Score. Measurement time points: Months 0, 12, 24, 36, and 48. Primary analysis: Change from month 0 to month 48. Primary safety outcomes [4-6]: [4] Withdrawals from the study protocol.
