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

aimReduced placental mTOR signaling is associated with intrauterine growth restriction and impaired maternal and placental metabolism. Since maternal hypothyroidism induces intrauterine growth restriction, and maternal treatment with kisspeptin-10 (Kp10) has been shown to improve feto-placental development in hypothyroid rats, this study aimed to evaluate the effects of maternal hypothyroidism, with and without kisspeptin-10 treatment, on maternal energy homeostasis and placental expression of mTOR and glucose metabolism mediators.

methodsMaternal hypothyroidism was induced by administration of propylthiouracil, and kisspeptin-10 treatment began on gestational day 8.

resultsMaternal hypothyroidism caused glucose intolerance, decreased insulin and HDL levels, reduced fetal and placental weights, and thinned the placental interhaemal barrier. It also increased INSRβ and AKT, while downregulating placental p-mTOR/mTOR and Glut1. Although kisspeptin-10 treatment did not improve maternal glucose homeostasis or prevent feto-placental growth restriction, it attenuated maternal hypothyroidism-induced placental Glut1 dysregulation, upregulated the IGF1/IGF1R axis, and restored placental AKT/mTOR expression.

conclusionThese findings suggest that kisspeptin-10 treatment in hypothyroid pregnant rats improves placental mTOR signaling and glucose metabolism mediators, highlighting novel pathways through which kisspeptin may modulate placental physiology.
