Serum 1,3-beta-D-glucan as a noninvasive test to predict histologic activity in patients with inflammatory bowel disease

Figure 4 Receiver operating characteristic curves illustrating the diagnostic ability of serum beta-glucan for detecting disease activity in patients with ulcerative colitis. Receiver operating characteristic curves are shown in relation to the (A) clinical; (B) endoscopic; (C) histologic; and (D) combined endoscopic and histologic criteria. Diagonal segments are produced by ties. The area under the curve with standard error and the 95% confidence interval (95%CI) are shown in each plot.
