Figure S9. Comparison of prevalence and mean relative abundance between NA-OTUs, PA-OTUs (strictly positive, PA; strictly negative, NA), and non-biomarkers. Mean relative abundances were scaled by taking their square root. (A) Sample quantities calculated across all samples. (B) Sample quantities stratified by body site, where PA- and NA-OTUs only include biomarkers for each respective body site. (PDF 3389 kb
