This includes both biomarkers that are specific indicators of IBD disease activity (C-Reactive Protein: −0.29 [95% CI: −0.47, −0.10]; Faecal Calprotectin: −0.19 [95% CI: −0.34, −0.03]), and generic markers of inflammation (composite analysis: −0.35 [95% CI: −0.48, −0.22]). This evidence concerns the gene CRP and inflammatory bowel disease.
