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

backgroundMII oocytes undergo time-dependent aging after ovulation, which is closely associated with impaired fertilization potential, poor embryo quality, and an increased risk of miscarriage. The apoptosis of cumulus cells and their secretion of TNF-α are identified as the primary contributors to postovulatory oocyte aging.

resultsIn this study, we demonstrated that astaxanthin supplementation in culture medium effectively prevents postovulatory oocyte aging and extends oocyte lifespan in vitro. Importantly, this protective effect does not operate through the inhibition of cumulus cell apoptosis or TNF-α release. Notably, astaxanthin selectively binds to TNFR2 in oocytes, thereby preventing TNFR2 from interacting with TNF-α and inhibiting the activation of the TNF signaling pathway within oocytes. Furthermore, oocytes cultured with astaxanthin exhibit enhanced potential for early embryonic development and significantly increased IVF-ET litter size compared to controls.

conclusionsOur findings, based on a mouse model, provide valuable insights into the potential clinical application of astaxanthin in mitigating post-ovulatory oocyte aging.
