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.
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
Background: Preeclampsia (PE) is a serious multisystem disorder that ranks among the leading causes of maternal and neonatal morbidity and mortality. The condition is characterized by an angiogenic imbalance, which has adverse effects on fetal development and contributes to an increased risk of cardiovascular disease in the long term. This study aims to explore the connection between sterile inflammation mediated by HMGB1 and angiogenic imbalance in PE by examining key markers such as HMGB1, VEGF, Decorin, and TGF-β. Methods: In an animal model of PE, we measured the levels of HMGB1, VEGF, Decorin, and TGF-β in plasma, placenta, and heart tissues using ELISA. Additionally, Decorin levels were assessed through immunofluorescence in trophoblasts. Results: We found that levels of Decorin and TGF-β were significantly elevated in the plasma, placenta, and heart tissues of PE animals compared to non-pregnant and pregnant controls, whereas VEGF levels were reduced. Treatment with Glycyrrhizic acid (GA) restored the expression levels of these markers to more normalized values in the PE groups. Conclusions: Our findings indicate that HMGB1 plays a critical role in preeclampsia by mediating the upregulation of anti-angiogenic factors like Decorin and the downregulation of angiogenic factors like VEGF. This study highlights a significant correlation between HMGB1 and Decorin in driving the angiogenic imbalance that contributes to the pathophysiology of PE.
