Causal Associations Between Gut Microbes and Heart Failure Across Multiple Etiologies: A Mendelian Randomization Study.
Article in Reviews in cardiovascular medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Gut microbiota are associated with heart failure (HF); however, the causal relationship between gut microbial communities and HF of varying etiologies remains incompletely established. Methods: This study leveraged two-sample Mendelian randomization (MR) to investigate whether genetically determined gut microbiota features causally influence HF and its related subtypes. Instrumental variables (IVs) for gut microbiota were derived from a large-scale, genome-wide association study (GWAS) of microbial traits conducted by the MiBioGen consortium, which included 18,340 individuals. Summary statistics for HF and its subtypes were extracted from the FinnGen Release 7, encompassing 19,350 all-cause HF cases and 288,996 controls. The Wald ratio and inverse-variance weighted analyses were applied to calculate the causal estimates. Results: A total of 19 single-nucleotide polymorphisms (SNPs) corresponding to 18 gut microbial taxa were selected as IVs. A significant inverse causal association was identified between the family Conclusions: Genetically predicted enrichment of
