Serum C-X-C motif chemokine ligand 9, interleukin 8, and interleukin 22 as key biomarkers in pediatric inflammatory bowel disease

Figure 1 Area under the receiver operating characteristic curve. A: Primary classification model discriminating between patients with inflammatory bowel disease (IBD) and without IBD including all 12 biomarkers; B: Variable importance in the final random forest model; C: Discriminative ability of each biomarker while adjusting for age and sex. AUC: Area under the curve; CI: Confidence interval; ROC: Receiver operating characteristic; CCL: C-C motif ligand; CXCL: C-X-C motif chemokine ligand; IL: Interleukin; TARC: Thymus and activation-regulated chemokine.
