Fig. 5. Receiver-operating characteristic (ROC) curves for the diagnosis of significant fibrosis in all, non-obese, and obese subjects.
ROC curves using the combination of two bacteria (Veillonellaceae and Ruminococcaceae) and four stool metabolites (CA, CDCA, UDCA, and propionate) were plotted for the diagnosis of significant fibrosis in a all, b non-obese subjects, and c obese subjects, and the areas under the ROC curves (AUCs) were calculated.
