Figure 2From: Diagnostic yield of endoscopy in patients with abdominal complaints: incremental value of faecal calprotectin on guidelines of appropriateness Diagnostic performance of faecal calprotectin testing. Receiver-operating characteristic (ROC) curve for clinically significant findings during EGD (dotted line) and colonoscopy (solid line). We also report the accuracy values for EPAGE criteria (EGD: open circle, colonoscopy: solid circle). The ROC curve represents the relationship between sensitivity and specificity for a considered outcome. EPAGE, European Panel on the Appropriateness of Gastrointestinal Endoscopy.Back to article page
