Fig. 6: Validation of gut-microbiome differences between non-obese and obese subjects using a Western NAFLD cohort.

a Abundance of Veillonellaceae and Ruminococcaceae stratified by obesity status and advanced fibrosis (*Pā=ā0.0120, nā=ā107 for non-obese, and nā=ā61 for obese). b ROC curves using the combination of two selected bacteria (Veillonellaceae and Ruminococcaceae) were plotted for the diagnosis of advanced fibrosis in non-obese and obese subjects, and the areas under the ROC curve (AUCs) were calculated. The box plots indicate the median, 25th to 75th percentiles (boxes), and 10th to 90th percentiles (whiskers). Statistical analysis was performed using a two-sided MannāWhitney test. *Pā<ā0.05. ns, not significant.
