Association between parental firefighting status and adverse birth outcomes in Arizona: a cross-sectional study.
Article in Occupational and environmental medicine, 2026. 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
backgroundFirefighters are continuously exposed to hazardous conditions including smoke, chemicals, stress, long work shifts and exhaustion, which may lead to a higher risk for chronic conditions and reproductive health issues. However, there is limited research looking at the association between parental firefighting with adverse birth outcomes. This cross-sectional study aimed to determine whether female or male firefighting was associated with adverse birth outcomes.
methodsArizona birth certificates for the years 2006-2013 were used to compare firefighters with teachers, law enforcement officers and all other occupations while stratifying by sex. Logistic regression models estimated ORs and 95% CIs.
resultsWe included 720 686 births, 5490 paternal firefighters and 376 maternal firefighters. Maternal firefighting was associated with increased odds of preterm birth compared with teachers (OR: 1.46, 95% CI 1.06 to 1.97) and all other occupations (OR: 1.41, 95% CI 1.02 to 1.88). Higher odds for neonatal intensive care unit admission were observed when compared with teachers (OR: 1.77, 95% CI 1.22 to 2.48), law enforcement officers (OR: 1.74, 95% CI 1.07 to 2.81) and all other occupations (OR: 1.84, 95% CI 1.30 to 2.56). Paternal firefighting was statistically significantly associated with decreased caesarean section and low birth weight.
conclusionsFemale firefighters may have higher odds of adverse birth outcomes. Further research should aim on understanding the biological mechanism behind these associations and ways to mitigate the risk in this population.
