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

Perimenopause marks initiation of female reproductive senescence. Age of onset is only 47% heritable suggesting that additional factors other than inheritance regulate this endocrine aging transition. To elucidate these factors, we characterized transcriptional and epigenomic changes across endocrine aging using a rat model that recapitulates characteristics of the human perimenopause. RNA-seq analysis revealed that hypothalamic aging precedes onset of perimenopause. In the hypothalamus, global DNA methylation declined with both age and reproductive senescence. Genome-wide epigentic analysis revealed changes in DNA methylation in genes required for hormone signaling, glutamate signaling, and melatonin and circadian pathways. Specific epignetic changes in these signaling pathways provide insight into the origin of perimenopause-associated neurological symptoms such as insomnia. Treatment with 5-aza-2'-deoxycytidine, a DNA-methyltransferase-1 inhibitor, accelerated transition to reproductive senescence/ whereas supplementation with methionine, a S-adenosylmethionine precursor, delayed onset of perimenopause and endocrine aging. Collectively, these data provide evidence for a critical period of female neuroendocrine aging in brain that precedes ovarian failure and that DNA methylation regulates the transition duration of perimenopause to menopause.
