Urinary parabens, advanced glycation end products and blood pressure in children: a longitudinal cohort study.
Article in Environmental research, 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
backgroundParaben exposure and advanced glycation end products (AGEs) have both been linked to cardiovascular conditions, including hypertension. However, the association between parabens and AGEs has not been studied yet. Parabens could affect blood pressure (BP) via AGEs.
methodsIn this longitudinal study, urinary paraben concentrations [methyl (MeP), ethyl (EtP), propyl (PrP), butyl (BuP)] were measured in preschool children from the ENVIRONAGE birth cohort using ultra-performance liquid chromatography/tandem mass spectrometry. BP and AGEs, assessed with skin-autofluorescence (SAF) z-scores, were measured at baseline (4 years) and six years later in 83 children (166 observations). First, generalized linear mixed models and quantile g-computation were applied to assess associations and mixture effects of parabens with AGEs and with BP. Next, structural equation modeling (SEM) was employed to disentangle time-specific effects in these associations and explore the role of AGEs as mediators in the relationship between parabens and BP.
resultsWe observed an inverse association between the paraben mixture and AGEs (β = -0.30 per quantile increase; 95 % CI: -0.55, -0.042), driven by PrP with the strongest negative weight. Single-pollutant models confirmed this association for PrP (β = -0.15; 95 % CI: -2.51, -0.049). SEM revealed direct effects of parabens on systolic blood pressure at 4 years (est.std. = 0.50; 95 % Boot CI: 0.10, 0.82). AGEs mediated an inverse indirect effect of parabens on DBP at 10 years (β = -0.21; 95 % Boot CI: -0.41, -0.05).
conclusionsEarly-life paraben exposure, particularly PrP, is associated with AGEs and blood pressure, warranting further investigation into long-term consequences.
