Epigenetic alterations in preeclampsia: a systematic review of current mechanisms and biomarker potential.

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
Preeclampsia (PE) remains a major cause of maternal and fetal morbidity and mortality worldwide, with placental dysfunction and angiogenic imbalance playing central roles in disease pathogenesis. Emerging evidence highlights epigenetic regulation and angiogenic biomarkers, including placental growth factor (PlGF), as key contributors to disease heterogeneity and risk stratification. A systematic review of studies published between 2022 and 2025 was conducted in accordance with PRISMA 2020 guidelines to synthesize current evidence on epigenetic mechanisms and biomarker potential in PE. In addition, a supplementary exploratory analysis was performed using laboratory-derived PlGF data to assess analytical variability and biological associations. Non-parametric methods were applied, including Mann-Whitney U testing to compare PlGF distributions by analytical sample classification and Kendall's tau correlation to evaluate associations with gestational age and the sFlt-1/PlGF ratio. The systematic review identified consistent epigenetic alterations involving DNA methylation, histone modifications, and non-coding RNAs across maternal and placental tissues. Supplementary analysis demonstrated significantly higher and more variable PlGF concentrations in analytically classified measured samples compared with accepted samples (
