Figure 2. Identification of predictive classifiers of “High” and “Low” inflammation subtypes of Crohn’s disease (CD) and ulcerative colitis (UC).

Figure 2

(A) A class predictor was built for both CD and UC using the tool Prophet and the 54,675 probes contained in the chip, using the leave-one-out cross-validation strategy. For each predictor, patients that were correctly classified are shown green, while those patients that the predictor failed to classify correctly are shown in red. (B) Based on the accuracy of each classifier, a 10-gene predictor was selected in both cases, which were able to accurately classify 92% of CD patients and 100% of UC patients. Up-regulated genes are shown in red and down-regulated in blue.
