1 · What the graph read from it

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.

2 · The registry

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

Mitochondrial DNA copy number (mtDNA-CN) reflects mitochondrial function and has been associated with several psychiatric disorders. However, the shared genetic architecture between mtDNA-CN and psychiatric conditions remains largely unexplored. Utilizing the largest available genome-wide association study (GWAS) summary statistics from individuals of European ancestry, we systematically investigated the shared genetic architecture between mtDNA-CN and five major psychiatric disorders, including attention deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD), bipolar disorder (BD), major depressive disorder (MDD), and schizophrenia (SCZ). Specifically, we assessed genetic overlap at the global, regional, and variant levels. In addition, gene expression analyses were performed to identify genes whose predicted expression was associated with both mtDNA-CN and psychiatric traits. Functional enrichment analyses were conducted to characterize the biological functions underlying the shared genes. Significant global-level genetic overlap was observed between mtDNA-CN and all five psychiatric disorders. Regional analyses identified four genomic regions with high pleiotropic probability shared between mtDNA-CN and ADHD, BD, and SCZ. At the variant level, 30 lead variants were detected, corresponding to 30 independent loci jointly associated with mtDNA-CN and psychiatric traits. These loci were mapped to 305 unique genes, among which 87 genes exhibited significant associations between their predicted expression levels and both mtDNA-CN and psychiatric disorders. Functional enrichment highlighted neurodevelopmental and ubiquitin-related pathways, with significant downregulation of shared genes in key brain regions. These findings provide comprehensive evidence for shared genetic mechanisms linking mitochondrial function and psychiatric disorders, highlighting mitochondrial dysfunction as a promising target for future therapy.
