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

Age-related decline in female fertility is a common feature that occurs in the fourth decade of women as a result of a reduction in both oocyte quality and quantity [1]. However, strategies to prevent the deterioration of maternal aged oocytes and relevant mechanisms are still underexplored. Here, we find that the reduced abundance of melatonin in the follicular fluid highly correlates with the advanced maternal age-related aneuploidy. Of note, we show that exposure of oocytes from aged mice both in vitro and in vivo to exogenous melatonin not only eliminates the accumulated reactive oxygen species-induced DNA damage and apoptosis, but also suppresses the occurrence of aneuploidy caused by spindle/chromosome defect that is frequently observed in aged oocytes. Importantly, we reveal that melatonin supplementation reverses the defective phenotypes in aged oocytes through a Sirt1/Sod2-dependent mechanism. Inhibition of Sirt1 activity abolishes the melatonin-mediated improvement of aged oocyte quality. Together our findings provide evidence that supplementation of melatonin is a feasible way to protect oocytes from advanced maternal age-related meiotic defects and aneuploidy, demonstrating the potential for improving the quality of oocytes from aged women and the efficiency of assisted reproductive technology.
