Comparative study between bowel ultrasound and magnetic resonance enterography among Egyptian inflammatory bowel disease patients

Figure 3 Receiver operating characteristic curve for prediction of active disease. A: At endoscopy, aphthous ulcers mean area under the receiver operating characteristic (ROC) curve was 0.875 (P < 0.001), positive likelihood ratio infinity, and negative likelihood ratio 0.28; B: Bowel ultrasound showed stricture and lymphadenopathy mean area under the ROC curve were 0.929 (P = 0.036) and 0.898 (P = 0.01) respectively, positive likelihood ratio infinity for both, and negative likelihood ratio 0.94 and 0.71 respectively; C: Magnetic resonance enterography showed thickness and proximal dilatation mean area under the ROC curve were 0.880 (P < 0.001) and 0.904 (P = 0.033) respectively, positive likelihood ratio 1.06 and infinity respectively, and negative likelihood ratio 0.88 for both.
