Attenuation of individual functions. a The density of attenuation values for each KEGG superpathway across all communities, with dots indicating the median attenuation. b A scatterplot of the median attenuation of each function in skin communities vs. gut communities. The color of each point indicates the difference in log median relative abundance of that function between skin and gut communities. The gray line indicates the 1:1 relationship in median attenuation. Only differentially abundant functions are show (FDR < 0.01; Wilcoxon rank-sum test). c Each point shows a function’s median attenuation in a particular environment with error bars displaying the 95% confidence interval and color indicating the environment
