Cervicovaginal microbiota diversity. (a,b) Principal Coordinate Analysis (PCoA) of Bray–Curtis dissimilarity for Amerindians among urbanization groups (low n = 15, medium n = 20, high n = 20) (a), and between ethnicities: Amerindians n = 15, mestizo n = 27, (PERMANOVA) (b). Gray lines connect samples with the group centroid. Ellipses indicate one standard deviation. (c,d) Alpha diversity using Shannon index among Amerindian urbanization groups (linear mixed-effect model, LMM) (c), and between ethnicities (Kruskal–Wallis test) (b). (e) Discriminant taxa analysis between ethnicities (LEfSe).
