a Baseline serum chemokine levels in responders (n = 16) and nonresponders (n = 13) to TNF inhibitor therapy. CXCL10 (p = 0.03) and CXCL13 (p = 0.002) levels were higher in responders than in nonresponders. The chemokine levels in the two groups were compared using Wilcoxon ranked sum test. Bars represent mean ± standard deviation. R responders, NR nonresponders. b Correlation between baseline CXCL10 and CXCL13 levels. Baseline CXCL10 and CXCL13 levels were highly correlated (r = 0.72, p = 0.00001). The association between the two chemokine levels was assessed using Spearman correlation
