Maternal dietary inflammatory index during pregnancy and the risk of offspring allergic disease.
Article in Pediatric allergy and immunology : official publication of the European Society of Pediatric Allergy and Immunology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
backgroundMaternal diet during pregnancy is considered a potential modifiable risk factor for allergic diseases in offspring. The dietary inflammatory index (DII) is a tool to assess the inflammatory potential of the diet and has been suggested to be associated with offspring allergy development. Its association with food allergy and immunoglobulin E (IgE) sensitization in children remains understudied.
methodsThis study analyzed 4709 mother-partner-child triads from the NorthPop Birth Cohort in Sweden. Maternal DII scores were calculated from a food frequency questionnaire administered at gestational week 34. Allergy outcomes at 18 months included parent-reported physician-diagnosed food allergy, parent-reported eczema and atopic eczema according to UK Working Party criteria, parent-reported ever wheeze, parent-reported physician-diagnosed asthma, and IgE sensitization to food and airborne allergens. Associations between maternal DII scores (continuous and quartiles) and allergic outcomes were assessed using logistic regression, adjusting for maternal age, allergic heredity, farm living, region of birth, siblings, and education.
resultsAt age 18 months, 4.9% of children had physician-diagnosed food allergy, 30.6% had eczema, 11.4% had atopic eczema, 15.9% reported ever wheeze, 4.1% had physician-diagnosed asthma, and 19% were IgE sensitized. No significant associations were found between maternal DII scores and the allergic outcomes of interest.
conclusionThis large birth cohort study found no association between maternal DII during pregnancy and allergic diseases or IgE sensitization in 18-month-old children, suggesting that a proinflammatory diet during pregnancy does not influence early allergic outcomes. Further research is needed to clarify the role of maternal diet in offspring immune development.
