Prenatal Exposure to Air Pollution and Pediatric Biliary Atresia: A Nationwide Population-Based Cohort Study.

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
introductionBiliary atresia (BA) is a serious pediatric liver disease and the leading cause of liver transplants in children. Although its cause is unknown, prior research suggests air pollution may influence childhood diseases. This study examines the potential association between prenatal air pollution exposure and BA incidence.
methodsThis nationwide, longitudinal matched case-control study used data from the National Health Insurance Research Database in Taiwan. BA cases were identified using ICD codes in children who underwent the Kasai procedure or liver transplantation. Controls, matched by age, index month, and gender, were selected at a 1:10 ratio. Multivariable logistic regression models, adjusted for potential confounders (age, gender, maternal age, delivery mode, and preterm birth), were utilized to assess the association between individual air pollutants (PSI, SO
resultsA total of 1,663,737 first-time pregnancies were identified from 2004 to 2016. After excluding 8,523 newborns due to congenital neonatal defects, 1,655,214 individuals remained. Among them, a cohort of 253 BA patients was identified. After adjusting for multiple confounders, no significant associations were found between prenatal exposure to air pollutants and BA risk. Quartile analysis of cumulative air pollutant exposure also indicated no dose-response relationship with BA risk for each air pollutant.
conclusionThis population-based study found no statistically significant association between prenatal air pollution exposure and the risk of BA in newborns in Taiwan.
