Performance measures of supervised machine learning models for classifying subjects with inflammatory bowel disease (IBD) and those without IBD (non-IBD) using gut microbiome features. Differential taxonomic features: area under the receiver operating characteristic curve (AUC) (A) and accuracy (B); high-variance OTU features: AUC (C) and accuracy (D). Each point in the box plot represents each performance measure in one iteration (total 50 iterations). OTU, operational taxonomic units.
