Fig. 5: Mediation analysis diagram illustrating the role of metabolic signatures in the relationship between mental health disorders and MASLD risk.
From: Association between mental health and MASLD molecular insights through metabolomics

The model tests whether metabolic alterations mediate the association between mental health exposures (anxiety, depression, mania, trauma) and MASLD. Percentages indicate the proportion of the total effect mediated by metabolic pathways. All indirect effects were statistically significant (P < 0.05).
