Phylogenetic mapping of top-ranked clade and OTU features. a Reference tree comprising all observed oral site OTUs, with branch lengths proportional to substitutions per site. Key phyla are highlighted with different colors. b–d Mapping of the highest-ranked clade and OTU features according to information gain (b, 110 features), chi-square (c, 170 features), and RF feature permutation (d, 100 features)
