Previous study showed that mucin-degraders (family Prevotellaceae) were enriched in patients with depression and anxiety 47 , and a further subgroup analysis of present study also supported a near-significant increase of Akkermansia in unaffected controls with antidepressant ( n = 5, P value = 0.056) when comparing to those without (Supplementary Fig. 9b ).
