Twelve-month outcome and baseline serum and cytokine expression. Twelve-month clinical data [rheumatoid factor (RF) titre, swollen joint count (SJC), tender joint count (TJC), disease activity score 28 (DAS28), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Larsen score and health assessment questionnaire (HAQ)] were correlated with cytokine expression and serum cytokine levels at baseline (Spearman's correlation, r). Parameters with significant correlations are plotted. The line of best fit using linear regression is shown (r2). Patients classified as rheumatoid arthritis (RA) are shown by open symbols, and undifferentiated arthritis (UA) by closed symbols. *P < 0·05; **P < 0·01.
