Figure 5. Kaplan–Meier survival analysis of the biomarkers fecal calprotectin and serum C-reactive protein as discriminative biomarker in Crohn’s disease (top) and ulcerative colitis (bottom). In Crohn’s disease the optimized cutoff value of fecal calprotectin 221 μg/g was associated with a treatment ‘incident’ within 48 weeks after infliximab induction treatment (p < .0001), whereas the corresponding optimized C-reactive protein cutoff 2.1 mg/L was not. In ulcerative colitis the optimized cutoff value of fecal calprotectin 221 μg/g was associated with a treatment ‘incident’ within 48 weeks after infliximab induction treatment (p < .0005), as was the corresponding optimized C-reactive protein cutoff level at 2.1 mg/L (p = .0334).
