Figure 4.

Efficacy of the serum leucine-rich alpha-2 glycoprotein (LRG) level as a biomarker for ulcerative colitis assessed using the Mayo endoscopic subscore (MES) (a) and for Crohn's disease assessed using the simple endoscopic score for Crohn's disease (SES-CD) (b). Receiver operating characteristic (ROC) curves for serum LRG and C-reactive protein (CRP) levels, as evaluated using the MES in ulcerative colitis (c) and the SES-CD in Crohn's disease (d). Values of the area under the ROC curve (AUC) are shown. Endoscopic remission was defined as MES ≤ 1 in UC and SES‐CD ≤ 4 in CD.
