Prenatal and postnatal exposure to organophosphate esters and replacement flame retardant mixtures and childhood respiratory outcomes.
Article in Environmental research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundEarly life exposure to single organophosphate esters (OPEs) and replacement brominated flame retardants (RBFRs) has been associated with adverse childhood respiratory outcomes, but the effects of OPE and RBFR mixtures are unknown.
methods377 pregnant women were recruited to the Health Outcomes and Measures of Environment (HOME) Study from 2003 to 2006 in Cincinnati, Ohio and later delivered singleton infants. We measured house dust OPEs and RBFRs prenatally at 20 weeks of gestation and postnatally at child age of 12 months and urinary OPEs prenatally at 16 and 26 weeks of gestation and at delivery and postnatally at child ages of 12 and 24 months. We performed Quantile G-computation (QG-computation) and Bayesian Kernel Machine Regression (BKMR) to assess the association of the exposure mixtures with wheeze and hay fever by child age of 5 years and evaluate the individual exposure effects and their interactions within the mixtures.
resultsIn QG-computation, a quartile increase in all urinary OPEs sampled at age 12 months was associated with 16% higher risk of wheeze (RR: 1.16, 95% CI: 1.01, 1.35). In BKMR, mixtures of prenatal OPEs and RBFRs, urinary OPEs at 16 weeks of gestation or 12 months of age and prenatal average urinary OPEs were associated with higher risk of childhood wheeze. Mixtures of prenatal average urinary OPEs were positively associated with childhood hay fever. When other exposures were fixed at their median value, prenatal dust tris(2-chloroethyl) phosphate (TCEP) and urinary bis(1,3-dichloro-2-propyl) phosphate (BDCIPP) were associated with higher hay fever risk, while dust prenatal tris(1-chloro-2-propyl) phosphate (TCIPP) was associated with lower risk.
conclusionsThese results suggest that early life exposure to OPE and RBFR mixtures may be risk factors for adverse respiratory outcomes in childhood.
