Saliva microbiome composition among 236 children grouped by body mass index percentile groupings. (A) Phylum-specific composition by mean relative abundance. (B) The composition of the top 10 genera based on the highest mean relative abundance across all samples. (C) The composition of the top 10 species based on the highest mean relative abundance across all samples. Color ranges (i.e., spectrum of blue for Streptococcus) for species are used to delineate species from the same genus. UW = underweight.
