Changes of gut microbiota compositions in HC and moderate and severe MDD patients. (A) Relative abundances of gut microbiota at the genus level in MDD patients and HC. (B) OPLS-DA model showed that there was only a small overlap between HC and moderate MDD patients, suggesting the divergent microbial changes between the two groups; (C) differential genera responsible for discriminating moderate MDD patients from HC; (D) OPLS-DA model showed that there was only a small overlap between HC and severe MDD patients, suggesting the divergent microbial changes between the two groups; (E) differential genera responsible for discriminating severe MDD patients from HC.
