Correlations between marker levels. Spearman correlation coefficients for all pairs of experimental markers as well as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are shown. Background colour indicates strength of association (red, >0.75; orange, 0.5–0.75; yellow, 0.25–0.5; white, <0.25).
