1 Does fecal calprotectin predict relapse in patients with Crohn's disease and ulcerative colitis? 
Valle García-Sánchez, Eva Iglesias-Flores, Raúl González, Javier P. Gisbert, José María Gallardo-Valverde, Ángel González-Galilea, Antonio Naranjo-Rodríguez, Juan F. de Dios-Vega, Jordi Muntané, Federico Gómez-Camacho  Journal of Crohn's and Colitis  Volume 4, Issue 2, Pages (June 2010) DOI: /j.crohns Copyright © 2009 European Crohn's and Colitis Organisation Terms and Conditions

2 Figure 1 Box graph representation of calprotectin determinations. The lower and higher limits of the box represent the first and the third quartiles, respectively. The black crossbar line in the box represents the median. The top and the bottom black crossbar lines represent the highest and the lowest values, respectively. The symbol ‘○’ indicated an isolated or extreme value. a) Basal calprotectin concentration and probability of subsequent relapse in all patients (p<0.01). b 1) Basal calprotectin concentration and probability of subsequent relapse in patients with CD (p<0.01). b 2) Basal calprotectin concentration and probability of subsequent relapse in patients with UC (p<0.01).

3 Figure 2 The area under the receiver operating characteristic (ROC) curve of calprotectin for predicting relapse in all patients was 0.72 (standard error=0.04).

5 Figure 4 a) Receiver operating characteristic (ROC) curve of calprotectin for predicting relapse in patients with CD. The area under the curve was 0.75 (standard error=0.06). The best cutoff value was 200µg/g (sensitivity 80%, specificity 65%, PPV 46%, and NPV 88%). b) Receiver operating characteristic (ROC) curve of calprotectin for predicting relapse in patients with UC. The area under the curve was 0.70 (standard error=0.06). The best cutoff value was 120µg/g (sensitivity 81%, specificity 63%, PPV 49%, and NPV 88%).
