Figure 2. Variation in gut microbiome composition.
Differentially abundant taxa among (a) countries and (b) obese group adjusted for BMI, age, sex and country using ANCOM-BC. Bars represent ANCOM-BC estimated log fold change between compared groups and error bars, with the 95% confidence interval. Representative ASVs with log fold change >1.4 in at least one group are shown for country. FDR-adjusted (p < 0.05) effect sizes are indicated by *, ** and ***, corresponding to p < 0.05, <0.01 and <0.001 respectively. n= 1694 samples. FDR= False Discovery Rate.
