CASP9 and inflammatory bowel disease: Caspase 9 concentration tended to be lower in patients with active IBD (3.51 ng/ml (1.69-7.28) vs. 12.85 ng/ml (2.14-77.2), p=0.080) and the difference was significant in UC patients (p=0.019) but not CD patients (p=0.815), also following the adjustment to protein concentrations (p=0.023 for UC).
