Comparison of fecal calprotectin levels and endoscopic scores for predicting relapse in patients with ulcerative colitis in remission

Table 3 Comparison of accuracy of relapse prediction between fecal calprotectin levels, Ulcerative Colitis Colonoscopic Index of Severity, Mayo Endoscopic Subscore, and Ulcerative Colitis Endoscopic Index of Severity

Factor	Sensitivity	Specificity	PPV	NPV	Accuracy
FC ≥ 323	0.500	0.933	0.833	0.737	0.760
UCCIS ≥ 10.2	0.750	0.898	0.667	0.930	0.867
MES 1	0.833	0.702	0.469	0.930	0.733
UCEIS ≥ 2	0.722	0.895	0.684	0.911	0.853

FC: Fecal calprotectin; MES: Mayo Endoscopic Subscore; NPV: Negative predictive value; PPV: Positive predictive value; UCCIS: Ulcerative Colitis Colonoscopic Index of Severity; UCEIS: Ulcerative Colitis Endoscopic Index of Severity.
