A The relative abundance of the most prevalent bacteria in phylum level in individual ADHD and healthy was shown. B The main phylum were Bacteroidota, Firmicutes, Proteobacteria, Actinobacteriota and Fusobacteriota in gut microbiome. C The Firmicutes-to-Bacteroidetes ratio (F/B ratio) in ADHD and HCs.
