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 can impair embryo development and offspring health, yet the mechanisms responsible remain poorly understood. In a high-fat diet (HFD)-based female mouse model of obesity, we identified a marked reduction of Stella (also known as DPPA3 or PGC7) protein in oocytes. Starting with this clue, we found that the establishment of pronuclear epigenetic asymmetry in zygotes from obese mice was severely disrupted, inducing the accumulation of maternal 5-hydroxymethylcytosine modifications and DNA lesions. Furthermore, methylome-wide sequencing analysis detected global hypomethylation across the zygote genome in HFD-fed mice, with a specific enrichment in transposon elements and unique regions. Notably, overexpression of Stella in the oocytes of HFD-fed mice not only restored the epigenetic remodeling in zygotes but also partly ameliorated the maternal-obesity-associated developmental defects in early embryos and fetal growth. Thus, Stella insufficiency in oocytes may represent a critical mechanism that mediates the phenotypic effects of maternal obesity in embryos and offspring.
