Mendelian-Randomization Study Reveals Causal Relationships Between Blood Metabolites and Psychiatric Disorders.
Article in Schizophrenia bulletin, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
background and hypothesisMetabolic dysregulation has been widely observed in psychiatric disorders. However, the causal relationships between metabolites and psychiatric disorders remain largely unknown. STUDY
designHere, we conducted bidirectional Mendelian randomization (MR) analyses to systematically investigate causal relationships between 8 psychiatric disorders (including attention deficit hyperactivity disorder (ADHD), anorexia nervosa (AN), anxiety, bipolar disorder (BIP), depression, posttraumatic stress disorder (PTSD), insomnia, and schizophrenia (SCZ)) and 1139 blood metabolites (including 823 metabolite levels and 316 metabolite ratios). STUDY
resultsIn forward MR, we identified 34, 21, 56, and 1 metabolites that are associated with BIP, SCZ, depression, and PTSD, respectively. Notably, several metabolites are associated with the risk of multiple psychiatric disorders. For instance, N2,N2-dimethylguanosine, 1,2-dipalmitoyl-gpc (16:0/16:0), and phosphatidylcholine acyl-alkyl C38:4 were negatively associated with the risk of SCZ and BIP. In reverse MR analyses, we explored the causal effects of psychiatric disorders on metabolites, and found that blood metabolites are also influenced by psychiatric disorders. For example, depression significantly affected 21 metabolite levels, including positively associated with 21-hydroxypregnenolone disulfate, and negatively associated with carotenoid.
conclusionsOur findings not only uncover the causal relationships between metabolites and psychiatric disorders, but also provide potential therapeutic targets for the prevention and treatment of these psychiatric disorders.
