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

Thyroid disorders cause abnormal puberty, indicating interactions between the hypothalamus-pituitary-thyroid (HPT) and hypothalamus-pituitary-gonadal (HPG) axes, which are important in pubertal development. The hypothalamic gonadotropin-inhibitory hormone (GnIH) was shown to be decreased in the early prepubertal stage, suggesting the role of GnIH on pubertal onset. Here, we investigated whether thyroid dysfunction affects pubertal onset in female mice via GnIH regulation. Hypothyroidism showed delayed pubertal onset with increased GnIH expression and reduced pituitary-gonadal activity. Remarkably, knockout of GnIH prevented the effect of hypothyroidism to delay the pubertal onset, resulting in indistinguishable pubertal timing in GnIH-knockout female mice between control and hypothyroidism-induced group, indicating that increased GnIH expression induced by hypothyroidism may lead to delayed puberty. In contrast, hyperthyroidism led to a decrease in GnIH expression, however pubertal onset was normal, implying further reduction of the inhibitory GnIH had little effect on the phenotypical change. Critically, thyroid hormone suppressed GnIH expression in hypothalamic explants and GnIH neurons expressed thyroid hormone receptors to convey the thyroid status. Moreover, the thyroid status highly regulated the chromatin modifications of GnIH promoter, H3acetylation and H3K9tri-methylation. These findings indicate a novel function of GnIH to mediate HPT-HPG interactions that contribute to proper pubertal development.
