Univariate analysis: IA treatment and follow-up tumour response (TR)

Medication exposure# of patientsWorse TR*OR95% CIP value
Systemic steroid alone2062.540.69 to 9.320.16
csDMARD1920.340.07 to 1.740.20

Any DMARD2440.650.17 to 2.470.53
NSAIDS alone710.610.07 to 5.580.66
  • *Worse TR: worsened tumour response on follow-up assessment as compared with baseline tumour response (eg, a patient with stable disease at baseline had progression of disease at follow-up).

  • bDMARD, biological disease-modifying antirheumatic drugs; csDMARD, conventional synthetic disease modifying antirheumatic drugs; IA, inflammatory arthritis; NSAIDs, non-steroidal anti-inflammatory drugs.
