Untargeted Urinary Metabolomic Profiling Reveals Metabolic Signatures Associated with Anhedonia Severity-Stratified Subgroups in Major Depressive Disorder
Objective To investigate urinary metabolite differences between subgroups stratified by anhedonia severity in patients with major depressive disorder (MDD) and identify potential biomarkers associated with anhedonia using untargeted metabolomic profiling. Methods Fifty-five MDD patients were recruited and stratified by...
