Association of umbilical cord blood phthalate levels with neonatal growth parameters in term pregnancies.

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
backgroundPrenatal exposure to endocrine-disrupting chemicals (EDCs), including di(2-ethylhexyl) phthalate (DEHP) and bisphenol A (BPA), has been associated with altered fetal growth. Umbilical cord blood provides a direct indicator of fetal exposure and may offer advantages over maternal urinary biomarkers.
objectiveTo examine the associations between cord blood concentrations of DEHP metabolites and BPA and neonatal anthropometric measures in term pregnancies.
methodsThis cross-sectional study included 84 singleton term mother–infant pairs. Cord blood DEHP metabolites and BPA were quantified using liquid chromatography–tandem mass spectrometry (LC–MS/MS). Birth weight, length, and head circumference were measured at delivery and expressed as sex- and gestational age–adjusted z-scores. Multivariable linear regression models adjusted for maternal age, pre-pregnancy body mass index, parity, smoking status, infant sex, gestational age and maternal occupation were applied. Exposure–response patterns were further explored using quartile-based analyses and restricted cubic spline models.
resultsDEHP metabolites were detected in 92.0% and BPA in 90.4% of cord blood samples. Higher ΣDEHP concentrations were associated with lower birth weight (β = − 0.24 SD), birth length (β = − 0.15 SD), and head circumference (β = − 0.11 SD; all p < 0.05). BPA exhibited a non-linear, threshold-type association, as confirmed by restricted cubic spline analyses, with lower birth weight and length observed only at higher exposure levels. No significant sex-specific interactions were identified.
conclusionHigher prenatal DEHP exposure, assessed using umbilical cord blood, was associated with modest yet consistent differences in neonatal growth parameters among term infants, whereas BPA demonstrated weaker and non-linear associations. These findings should be interpreted within an observational framework and do not imply causality. These findings underscore the relevance of prenatal exposure to common endocrine-disrupting chemicals for early human growth.
