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

Figure 2 Although no difference was found in the beta-glucan levels regarding clinical activity, significant differences were shown for the endoscopic activity in the Crohn’s disease group and for histologic activity and combined endoscopic and histologic activity for both the Crohn’s disease and ulcerative colitis groups. Serum beta-glucan concentrations are stratified in Crohn’s disease and ulcerative colitis according to (A) clinical; (B) endoscopic; (C) histologic; and (D) combined endoscopic and histologic indexes. The analysis was performed by the Mann-Whitney rank-sum test. The horizontal bars represent medians, and the boxes represent the 25^th and 75^th percentiles. Significant results are depicted (^aP = 0.002; ^bP < 0.001; ^cP = 0.013; ^dP < 0.001; ^eP = 0.047).
