Gut microbiome community architecture in MSM and non-MSM
(A) Alpha diversity analysis of MSM compared to non-MSM (adjusted by fixed-effect linear models,31 Shannon diversity padj = 0.017, richness padj = 0.237).
(B) Principal-coordinate analysis (PCoA) based on microbial abundance profiled using MetaPhlAn 425 between MSM and non-MSM samples (PERMANOVA, R2 = 0.042 and padj< 0.001). Marginal density plots show distributions of samples along each axis. MSM N = 93, non-MSM N = 31.
