Leucine-rich alpha-2 glycoprotein as a superior biomarker to C-reactive protein for detecting small bowel lesions in Crohn’s disease

Figure 5 Receiver operating characteristic analysis of each parameter in predicting the endoscopic activity in the colon and ileum. The area under curves of leucine-rich alpha-2 glycoprotein, C-reactive protein, albumin, and Harvey-Bradshaw index in the colon were relatively high. Conversely, in the ileum, all of these values were lower than those in the colon; however, only leucine-rich alpha-2 glycoprotein remained relatively high. A-D: Receiver operating characteristic analysis of each parameter in predicting the endoscopic activity in the colon; E-H: Receiver operating characteristic analysis of each parameter in predicting the endoscopic activity in the ileum. LRG: Leucine-rich alpha-2 glycoprotein; CRP: C-reactive protein; HBI: Harvey-Bradshaw index; AUC: Area under curves.
