Beta diversity differences by alcohol of choice groups

A–C. Principal Components Analysis (PCA) plots of oral microbiome samples, performed at the taxonomic level of genus and based on Bray-Curtis dissimilarity stratified by alcohol of choice groups. Overall gut microbial community structure differences between alcohol of choice groups varied by sample, as determined by analysis of similarity (ANOSIM) analysis, at A: day 4 (R = 0.189, P = 0.035), B: day 7 (R = 0.170, P = 0.035) and C: week 2 (R = 0.158, P = 0.049)
