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

Preeclampsia (PE) remains a major contributor of maternal and fetal morbidity and mortality worldwide, affecting 2%-8% of pregnancies. While genetic predisposition, placental dysfunction, and angiogenic imbalance remain central to PE pathophysiology, emerging observational evidence suggests potential associations between environmental factors, epigenetic modifications, and PE development. This review consolidates available research linking environmental exposures, particularly air pollution, maternal gut microbiome composition, and dietary habits, with changes in epigenetic markers during pregnancy that may influence PE susceptibility. We synthesize findings from epidemiological studies, mechanistic research, and biomarker studies across this research area. However, definitive causal evidence linking specific environmental exposures to PE through epigenetic mechanisms remains limited. The majority of existing studies employ observational designs or focus on biological mechanisms; well-designed prospective cohorts incorporating direct environmental measurements and randomized intervention trials are lacking. Circulating biomarkers, including microRNAs and DNA methylation patterns, show associations with both PE status and prior environmental exposure, providing biological support for the concept that environmental factors may influence PE development. The maternal gut microbiome demonstrates dysbiosis in PE patients, and mechanistic studies in animal models suggest that microbiota-derived metabolites may influence placental development through epigenetic pathways; however, clinical evidence in humans remains preliminary. Integration of environmental exposure assessment with multi-omics profiling in large prospective studies is necessary to establish whether environmental factors causally contribute to PE pathogenesis. Future research combining detailed environmental characterization, longitudinal epigenomic profiling, and rigorous causal inference methods will be essential to translate these mechanistic insights into prevention and therapeutic strategies.
