Blood Metabolome Mediates the Effect of the Plasma Lipidome on the Risk of Atrial Fibrillation: A Mendelian Randomization Study.
Article in Clinical cardiology, 2025. 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
objectiveAtrial fibrillation (AF), a common arrhythmic disorder, is increasing in prevalence annually and has become an important public health problem that jeopardizes human health. Metabolites are small molecules produced in the process of metabolic reactions, and they can affect the risk of disease and possibly become targets for disease management.
methodsWe used two-sample and bidirectional MR to explore potential causal associations between lipid groups and AF. Two-step MR analysis was used to explore whether plasma metabolites mediated a causal effect from lipidomes to AF.
resultWe assessed the effect of 179 lipids on AF using IVW models and observed that 8 lipids were associated significantly with AF (p < 0.05). Likewise, we assessed the effect of 1091 metabolites and 309 metabolite ratios on AF and observed that 22 metabolites were significantly associated with AF (p < 0.05). We analyzed the blood metabolites above as mediators in the pathway from the lipidomes above to AF. We found that levels. Of lipid sterol ester (27:1/18:3) were associated with lower homoarginine levels, and lower metabolite homoarginine levels were associated with an increased risk of AF.
conclusionOur study identified a causal relationship between plasma liposomes and AF, and additionally found that the plasma metabolite homoarginine levels can act as a mediator of the lipid sterol ester in its effect on AF.
