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

problemIntrauterine growth restriction (IUGR) is a pregnancy complication characterized by failure of the fetus to reach its genetic growth potential. We established the association Klotho, fibroblast growth factor 23 (FGF23), and vascular endothelial growth factor receptor 2 (VEGFR2) with IUGR for the first time, hoping to provide new insights for its diagnosis and treatment. METHOD OF STUDY: Sixteen pregnant rats were randomly divided into a low-protein diet group (IUGR group) and a control group. Placental tissues were sampled to detect Klotho, FGF23, VEGFR2 mRNA, and protein expression in placental tissues of pregnant rats using quantitative real-time polymerase chain reaction (qRT-PCR) and western blot. Bioinformatics methods were also used to predict the signaling pathways involved in Klotho, FGF23, and VEGFR2.

resultsThe weight and crown-rump length of fetal rats in the IUGR group were significantly lower than those in the control group (p < 0.05). The expression levels of Klotho, FGF23, and VEGFR2 in IUGR group placental tissues were significantly lower than those in the control group (p < 0.05). Meanwhile, based on bioinformatics, it was predicted that VEGFR2 might affect the activation of the PI3K/AKT signaling pathway by growth hormone (GH)/insulin-like growth factor-1(IGF-1) through Klotho/FGF23 axis inhibition.

conclusionsIUGR caused by a low protein diet reduced birth weight and crown-rump length and low expression of Klotho, FGF23, and VEGFR2 in placental tissues, which may inhibit fetal growth through the VEGFR2-Klotho-FGF23-GH-IGF-1-PI3K-AKT signaling axis.
