Neonatal vitamin D status and asthma risk after age 5 years: A Danish 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
backgroundVitamin D may play a role in early lung development, yet epidemiologic evidence on its association with later asthma risk is mixed. We aimed to investigate the associations of neonatal 25-hydroxyvitamin D (25(OH)D) and vitamin D-binding protein (DBP) and their corresponding genetic predictors with asthma risk.
methodsWe conducted a population-based cohort study of a random sample of individuals born in Denmark during 1991-2005 from the iPSYCH2012 study. Neonatal concentrations of 25(OH)D and DBP were measured via dried blood spots, and asthma cases were identified through diagnoses or asthma prescriptions after age 5 years. Cox regression was used to estimate hazard ratios (HRs) for asthma in relation to 25(OH)D, DBP, and polygenic scores (PGSs) for these traits and asthma to assess genetic liability to vitamin D status and asthma.
resultsOf 14,005 individuals, 2308 (16.5%) developed asthma over a maximum follow-up of 25 years. We found no association between neonatal 25(OH)D (HR = 1.04, 95% CI: 0.99-1.09 per SD increase) or DBP (HR = 1.01, 95% CI: 0.97-1.05) and asthma risk. Analyses using tertiles to assess potential non-linear associations yielded similar null results. A higher asthma PGS was associated with increased asthma risk (HR = 1.42, 95% CI: 1.36-1.47 per SD increase), whereas PGSs for 25(OH)D (HR = 1.00, 95% CI: 0.96-1.05) and DBP (HR = 0.99, 95% CI: 0.95-1.04) were not.
conclusionsOur study suggests that neonatal vitamin D status is not associated with asthma risk. Similarly, genetic liability related to vitamin D status, as reflected in PGSs for 25(OH)D and DBP, is not associated with an increased risk of asthma.
