Variable Value
Female 9 (75)
Male 3 (25)
Age, years, median (IQR) 47 (37 to 57)
Disease duration, months, median (IQR) 7.2 (4.9 to 9.5)
Rheumatoid factor 5 (41.6)
Anti- cyclic citrullinated peptide 4 (33.3)
Disease activity score in 28 joints (ESR) 5.41 (4.46 to 6.34)
Inflammatory markers  
Erythrocyte sedimentation rate 43 (31 to 55)

  1. All patients were recruited form an early arthritis clinic with symptom onset <1 year and mean disease activity score in 28 joints of 5.41. Disease duration taken from the onset of initial symptoms: 42% of patients were rheumatoid factor-positive, 33% were anti-cyclic citrullinated peptide-positive. A third of patients were receiving anti-inflammatory medication prior to recruitment. Numbers are reported with percentage, otherwise, mean and IQR are given where specified.
