  1. A = Assessed; − = not assessed; TJC = tender joint count; SJC = swollen joint count; anti-CCP = anti-citrullinated peptide; IgM-RF = IgM-rheumatoid factor; VAS = visual analog scale; HAQ = health assessment questionnaire; SF-36 = short form (36) health survey; EQ-5D = EuroQol; DAS28 = disease activity score based on assessment of 28 joints; MRI = magnetic resonance imaging; MCP = metacarpophalangeal joints.
  2. *Right and left shoulder joints, elbow joints, wrists, MCP joints, PIP joints, 1st IP joint, knee joints, ankle joints and MTP joints.
  3. **Inspection of the cavum oris, skin, assessment of lymph node status, heart and lung stethoscopy, examination of the abdomen, neurological examination and additional focused examinations if the patient’s medical history suggests presence of other disease.
  4. ***Hemoglobin, leucocytes and differential count, CRP, thrombocytes, albumin, creatinine, electrolytes, alkaline phosphatases, alanine amino transaminase. Furthermore, anti-CCP and IgM-RF are also analyzed at baseline and subsequently repeated at months 12 and 24.
  5. ****DAS28-4(crp) = 0.56*sqrt (tender joint count 28) + 0.28*sqrt (swollen joint count 28) + 0.36*ln (CRP + 1) + 0.014*GH + 0.96.
  6. *****If technically possible.
