Fig. 1: Comparison of gut microbiota between patients and HCs.

A Species differences of gut microbiota at the species level in patients with MDD and HCs, Note:log2(MDD:HC) represents the log2-transformed value of the abundance ratio between the MDD group and the HC group for each species. B Alpha diversity of gut microbiota at the genus level in the patients with MDD and HCs. C Alpha diversity of gut microbiota at the species level in the patients with MDD and HCs. D Beta diversity of gut microbiota at the genus level in the patients with MDD and HCs. E Beta diversity of gut microbiota at the sepcies level in the patients with MDD and HCs.
