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
backgroundAcute lymphoblastic leukemia (ALL) is the most common type of cancer among children. Tobacco exposure during gestation has been investigated as a potential risk factor, but its role remains undefined. Given tobacco's toxicologic profile as a DNA-damaging agent, we examined the impact of DNA repair gene variability as a source of vulnerability to tobacco exposure risk for ALL.
methodsLeveraging demographic and genotype data from two large California-based ALL epidemiology studies, we used logistic regression, MinimumP (minP) statistical method, and permutation tests to examine interactions between DNA repair genes and prenatal tobacco exposure.
resultsWe found statistically significant interactions between prenatal tobacco exposure and DNA repair genes RECQL (minP = 1.00 × 10-4, FDR-P value = 1.86 × 10-2) and TDG (minP = 1.00 × 10-4, FDR-P value = 1.86 × 10-2) with regard to childhood ALL risk. Notable interactions in the homologous recombination pathway were observed among Latino children, whereas non-Latino White children displayed significant interactions in the base excision repair and nucleotide excision repair pathways.
conclusionsOur study highlights the significance of DNA repair genes and pathways when evaluating environmental exposure to tobacco smoke, suggesting that genetic variability within these pathways could impact vulnerability in the development of childhood ALL. IMPACT: This study highlights the significant impact of genetic variation interacting with prenatal tobacco exposure on ALL risk. Further research is needed to understand these interactions and their implications for ALL etiology. Expanding studies to other gene-environment interactions will aid in developing targeted prevention, diagnosis, and treatment strategies for pediatric oncology.
