Association of Prenatal Polycyclic Aromatic Hydrocarbons Exposure, DNA Hydroxymethylation, and Neurodevelopment at 0 and 2 Years of Age.
Article in Toxics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Maternal exposure to polycyclic aromatic hydrocarbons (PAHs) during pregnancy may have effects on the offspring epigenome. And the change in onset epigenome may be associated with children's neurodevelopment. The current study investigated the relationship between 5-hydroxymethylcytosine (5-hmC) levels in cord blood and PAH metabolites in maternal urine at delivery and children's neurodevelopment at birth and at age 2. We enrolled 400 pregnant women and their newborns and collected their biological samples after obtaining written informed consent. Enzyme linked immunosorbent assay kits and Chromatin immunoprecipitation kits were used to assess the DNA hydroxymethylation level in cord blood. We observed that 1-hydroxypyrene (1-OHPyr) was inversely associated with gesell developmental scale scores, positively associated with global DNA 5-hmC levels, and associated with decreased 5-hmC levels of the brain-derived neurotrophic factor (
