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

Maternal obesity is linked to heightened metabolic disease risk in offspring, but the mediators of this intergenerational effect remain unclear. Using a diet-induced obesity (DIO) mouse model, we showed that maternal circulating small extracellular vesicles (sEVs) crossed the placenta and delivered obesity-associated miRNAs to the fetal liver, with lasting consequences for insulin sensitivity in male offspring. Among these miRNAs, miR-29a-3p was pathologically elevated and targeted both DNA methyltransferases and demethylases, thereby reshaping the DNA methylation landscape. This included hypomethylation of the Pgc-1α locus, a key regulator of gluconeogenesis, which resulted in premature activation of hepatic gluconeogenesis that contributed to the persistent metabolic dysfunction in adulthood in male offspring. These findings identify a transplacental sEV-miRNA-epigenetic axis that perturbs fetal metabolic programming and may represent a conserved mechanism underlying the developmental origins of metabolic disease.
