Core Tip
Core Tip: Our study reported metabolites (some lipids, steroids, amino acids, carnitines, and alkaloids) responsible for discriminating major depressive disorder (MDD) patients and healthy controls. This metabolite signature may facilitate the development of a laboratory-based diagnostic test for MDD. The mechanisms underlying the association between psychological or clinical variables and differential metabolites deserve further exploration.
