Figure 4From: Differential expression of pro-inflammatory cytokines IL-15Ralpha, IL-15, IL-6 and TNFalpha in synovial fluid from Rheumatoid arthritis patientsCorrelation between IL-15Ralpha in SF from RA patients and ERS, PCR and DAS28. Correlations of IL-15Ralpha concentration and DAS28, CRP and ERS were analyzed using spearman’s rank correlation. Correlations were significant IL-15Ralpha and DAS28 (A), but not for CRP and ERS (B and C).Back to article page
