a The abundances of genes involved in vitamin B12 metabolism differed significantly between children and adults. Enrichment of KO groups (White’s non-parametric t-test, q < 0.10) is indicated by color (green: children; blue: adults). b Child and adult metagenomic profiles could be differentiated from one another at the pathway level. KEGG pathways with the greatest Random Forests importance scores are highlighted here
