  1. *Swollen joint count based on inflammatory arthritis (IA) patients, as all clinically suspect arthralgia (CSA) patients per definition do not have swollen joints
  2. ACPA anti-citrullinated peptide antibody (anti-CCP2, EliA CCP, Phadia, the Netherlands, positive if ≥ 7 U/mL), RF immunoglobulin M-rheumatoid factor (positive if ≥ 3.5 IU/mL), CRP c-reactive protein (positive if ≥ 5 mg/L), SD standard deviation, IQR inter quartile range
