Using this composite IBD endoscopy score (see Supplementary Table 2; n = 71), significant correlations were observed for Eotaxin-1 (ρ = 0.316, P < 0.01), IL-8 (ρ = 0.295, P < 0.05) and SAA (ρ = 0.288, P < 0.05) (Supplementary Figure 1). The gene discussed is CCL11; the disease is inflammatory bowel disease.
