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

Figure 1 Association between fecal calprotectin and endoscopic scores. A: Differences in fecal calprotectin (FC) levels between Mayo Endoscopic Subscore (MES) groups; B: Differences in the Ulcerative Colitis Colonic Index of Severity (UCCIS); C: Correlation with the Ulcerative Colitis Endoscopic Index of Severity; D: Relationship between FC and UCCIS; E: Correlation between FC and UCCIS. ^aP < 0.001.

Figure 2 Receiver-operating characteristic analysis of fecal calprotectin and Ulcerative Colitis Colonic Index of Severity for predicting Mayo Endoscopic Subscore 0. FC: Fecal calprotectin; UCCIS: Ulcerative Colitis Colonic Index of Severity.

Figure 3 Differences between fecal calprotectin and Ulcerative Colitis Colonic Index of Severity in terms of predicting relapse and the receiver-operating characteristic analysis for predicting relapse. A: Difference in fecal calprotectin (FC) levels between the relapse and remission groups; B: Difference in Ulcerative Colitis Colonic Index of Severity (UCCIS) between the relapse and remission groups; C: Receiver-operating characteristic analysis of FC and UCCIS for predicting relapse within 1 year. ^aP < 0.001. FC: Fecal calprotectin; UCCIS: Ulcerative colitis colonic index of severity.

Figure 4 Kaplan-Meier analysis of relapse-free rates. A: Mayo Endoscopic Subscore; B: Ulcerative Colitis Endoscopic Index of Severity; C: Fecal calprotectin levels; D: Ulcerative Colitis Colonic Index of Severity. FC: Fecal calprotectin; MES: Mayo endoscopic subscore; UCCIS: Ulcerative colitis colonic index of severity; UCEIS: Ulcerative colitis endoscopic index of severity.
