Externalizing behaviors in children living near coal-fired power plants.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundProximity to coal-fired plants exposes children to neurotoxic metals, which can negatively impact their behavioral health. Our research team previously reported an association between coal fly ash exposure and depression. However, other neurobehavioral outcomes have not been assessed. We hypothesized that the presence of fly ash would be associated with increased externalizing behaviors in children aged 6-14 years old.
methodsThis was a community-basedcross-sectional study. To investigate the association between externalizing behaviors and fly ash, five externalizing behavior scales and the composite Externalizing Problems scale from the Child Behavior Checklist (CBCL) were examined. Air samplers were placed in children's homes to collect fly ash which was determined by scanning electron microscopy. Generalized linear regression with a negative binomial distribution and logistic regression were conducted to assess the association between fly ash and the results from the CBCL.
resultsApproximately 43% of children had detectable levels of fly ash in their homes. The odds of exhibiting clinically significant externalizing problems (t-score ≥ 65) after being exposed to fly ash was 2.66 times higher (95% confidence interval (CI) 1.08 to 6.57) compared to children who were not exposed. Though not statistically significant, Conduct Problems were 34% higher (95% CI: 0.885, 2.021) and Rule-Breaking Behavior was 22% higher (95% CI: 0.872, 1.696) among children exposed to fly ash compared to those who were not exposed.
conclusionsBased on our findings, fly ash may be a potential risk factor for externalizing behaviors in children living near coal-fired power plants. While a cross-sectional study design does not provide the opportunity to prove a causal relationship, it can generate hypotheses that inform more rigorous epidemiological studies for further investigation of the observed associations.
