Infliximab trough level combined with inflammatory biomarkers predict long-term endoscopic outcomes in Crohn’s disease under infliximab therapy

Figure 3 Receiver operator characteristic curve of infliximab trough level and inflammatory biomarkers in predicting endoscopic outcomes. A: Receiver operator characteristic (ROC) curve of infliximab trough level at week 14 in predicting endoscopic remission of Crohn’s disease (CD) at week 54; B: ROC curve of fecal calprotectin at week 14 in predicting endoscopic remission of CD at week 54; C: ROC curve of infliximab trough level at week 54 in predicting endoscopic remission of CD at week 108; D: ROC of C-reactive protein at week 54 in predicting endoscopic remission of CD at week 108. ITL: Infliximab trough level; CRP: C-reactive protein; FCP: Fecal calprotectin; AUC: Area under the curve.
