Childhood cancer risk in offspring of mothers occupationally exposed to hydrocarbon solvents.

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
Little is known about maternal occupational exposure to hydrocarbons and offspring cancer risk. We aimed to estimate childhood cancer risk associated with maternal exposure to aliphatic/alicyclic, aromatic, and chlorinated hydrocarbons, and methylene chloride, trichloroethylene, 1,1,1-trichloroethane, and toluene. In this case-control study, all cancer cases ( N = 10 442) diagnosed at less than 20 years (born 1968-2016) in Denmark were matched to 261 050 cancer-free controls (25 : 1 matching ratio). Maternal exposure during pregnancy was determined from a job-exposure matrix. We performed unconditional logistic regression to estimate cancer risks from hydrocarbon exposures, adjusting for maternal age, maternal birthplace, and the child's birthplace. For medulloblastoma, we observed strong associations with maternal occupational exposure to chlorinated hydrocarbons [adjusted odds ratio (aOR): 2.33, 95% confidence interval (CI): 1.29-4.20] including the individual solvents: trichloroethylene (aOR: 1.76, 95% CI: 1.08-2.88) and methylene chloride (aOR: 1.62, 95% CI: 0.98-2.68). The risk of medulloblastoma also increased with maternal exposure to aliphatic/alicyclic hydrocarbons (aOR: 1.78, 95% CI: 0.99-3.20), aromatic hydrocarbons (aOR: 1.64, 95% CI: 0.93-2.89), and toluene (aOR: 1.83, 95% CI: 1.04-3.22). The risk of non-Hodgkin lymphoma (NHL) increased with exposure to chlorinated hydrocarbons (aOR: 1.95, 95% CI: 1.09-3.51). The strongest association with acute lymphoblastic leukemia (ALL) was observed for aromatic hydrocarbons (aOR: 1.35, 95% CI: 1.07-1.71). We saw increased risks in medulloblastoma, NHL, and ALL in offspring of mothers occupationally exposed to solvents in pregnancy over a span of 50 years in Denmark. We encourage maternal workplace safety measures that reduce exposures in pregnancy to improve children's health.
