Partial constrained analysis of principal coordinates (CAP) and Principal Coordinate Analysis (PCoA) plots. a, b CAP plots using unweighted and weighted UniFrac phylogenetic distance matrices in all study participants. Drinking level was the constraining variable; age, race, gender, BMI, education, smoking status, and study were treated as partial variables. Filled shapes indicate centroids for each group. c, d Bar plots showing the means of the first, second, and third coordinates of PCoA for each drinking level using unweighted and weighted UniFrac phylogenetic distance matrices in all study participants. One star (*) indicates p < 0.05 in the Kruskal-Wallis post hoc test (Dunn’s test)
