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

Background: People with severe mental illness (SMI) have shorter life expectancy, largely driven by physical health conditions. While lifestyle and psychotropic side effects contribute, peripheral organ dysregulation is intrinsic to SMI. Clarifying these effects could reveal novel therapeutic targets. Methods: Mendelian randomization (MR) was used to test the causal effects of genetic liability to schizophrenia, bipolar disorder, and major depressive disorder (MDD) on magnetic resonance imaging (MRI)-derived measures of peripheral organ structure and composition. Multivariable MR assessed lifestyle and metabolic mediators. One-sample MR and observational analyses in the UK Biobank (UKB) explored sex-specific effects. Two-sample MR used the largest genome-wide association study (GWAS) for schizophrenia ( Results: Genetic liability to all 3 SMIs associated with reduced peak diastolic strain rates, indicating impaired myocardial relaxation. Schizophrenia liability associated with smaller ventricular volumes, larger lung volumes, and higher liver iron levels. Bipolar disorder liability associated with lower right-sided cardiac volumes; higher left ventricular mass-to-volume ratio; and increased visceral, subcutaneous, and organ fat. MDD liability predominantly associated with greater abdominal and organ fat. Associations persisted after adjustment for body mass index, inflammation, insulin resistance, and smoking. One-sample MR in the UKB was directionally consistent and suggested sex-specific effects. Conclusions: SMI genetic liability exerts both shared and disorder-specific causal effects on peripheral organ structure, with myocardial stiffening (indicating poor cardiovascular prognosis) common to all, cardiopulmonary changes in schizophrenia, adipose-organ changes in MDD, and an intermediate phenotype in bipolar disorder. These cardiometabolic alterations support integrated screening and prevention strategies targeting cardiovascular and metabolic risk in SMI.
