Association between vitamin D status in early pregnancy and atopy in offspring in a vitamin D deplete cohort.
Article in Irish journal of medical science, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 status may play a role in the development of atopic diseases due to its action on lung development and immune system development and function.
aimsOur objective was to assess whether 25-hydroxyvitamin D (25OHD) levels in maternal blood in pregnancy were associated with atopy in children.
methodsWe analysed 279 mother-child pairs from the ROLO study conducted in Dublin, Ireland. Serum 25OHD was measured at 13 and 28 weeks of pregnancy. Development of childhood atopy was self-reported by mothers at follow-up appointments at 6 months, 2 years or 5 years. Logistic regression analysis was used to evaluate associations between maternal 25OHD status and development of atopy.
resultsThe mean (SD) 25OHD levels in early and late pregnancy were 41.9 (19.2) nmol/L and 40.2 (21.6) nmol/L, respectively. Maternal 25OHD status in early pregnancy, but not in late pregnancy, was associated with a reduced risk of atopy at 2 years (OR 0.972, CI 0.946-0.999). In early pregnancy, those with serum 25OHD levels < 30 nmol/L compared with those with 25OHD > 50 nmol/L had significantly greater risk of developing atopy at 2 years (OR 4.76, CI 1.38-16.47).
conclusionsThe development of childhood atopy may be associated with maternal vitamin D deficiency in early pregnancy among a cohort of women at risk of vitamin D deficiency. Further research is required to explore the relationship between vitamin D and atopy, particularly among women with poor vitamin D status, and whether supplementation should be prioritised in early pregnancy to reduce childhood atopy.
