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

objectiveThis study aimed to test the hypothesis that the NCOR2/DLL-4/Jagged-1 axis is dysregulated in cord blood of offspring from mothers with preeclampsia (PE) and gestational hypertension (GH), favoring an anti-angiogenic profile. We compared expression levels of these Notch pathway components among PE, GH, and healthy control groups to explore their potential role in fetal vascular programming.

methodsThis is a prospective cohort study, including 17 mother-offspring pairs with gestational hypertension, 17 mother-offspring pairs with preeclampsia, and 34 healthy mother-offspring pairs as controls. Standardized questionnaires were used to collect family and birth information, medical records were used to collect clinical data, and Western blot was employed to measure the expression levels of NCOR2, DLL-4, and Jagged-1 in cord blood. We analyzed the differences in offspring cord blood proteins among the three groups.

resultsCord blood protein expression revealed significant dysregulation of the NCOR2/DLL-4/Jagged-1 axis. Compared to the control group (1.36 ± 0.44), the GH (1.00 ± 0.12) and PE (0.94 ± 0.15) groups were characterized by a significant downregulation of NCOR2 (p = 0.001). Furthermore, a progressive and significant increase in DLL-4 (p = 0.001) was observed across the control (0.82 ± 0.28), GH (0.98 ± 0.17), and PE (1.27 ± 0.40) groups, which was accompanied by a significant stepwise decrease in Jagged-1 expression (control: 1.36 ± 0.28, GH: 1.02 ± 0.12, PE: 0.87 ± 0.18, p < 0.001).

conclusionThe cord blood levels of NCOR2 and Jagged-1 proteins were significantly decreased in offspring of PE and GH, while DLL-4 protein expression was significantly increased in offspring of PE. These findings suggest that dysregulated Notch signaling, characterized by an anti-angiogenic profile in the fetal circulation, may contribute to the vascular programming observed in offspring of preeclamptic pregnancies.
