Impact of maternal organic food consumption and diet quality during pregnancy on offspring's risk of inflammatory bowel disease: findings from a Danish National Birth 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
Background: This study explores associations of maternal organic food consumption and diet quality during pregnancy with pediatric-onset inflammatory bowel disease (IBD) risk in offspring, including Crohn's disease (CD) and ulcerative colitis (UC). Methods: Pregnant mothers and their offspring were enrolled in the Danish National Birth Cohort, a nationwide prospective cohort study, in 1996-2002. In gestational week 30, telephone interviews assessed overall maternal organic food consumption during pregnancy. In gestational week 25, a food frequency questionnaire assessed maternal diet during the previous 4 weeks, including six different organic food types (eggs, dairy, meat, fruit, vegetables, and cereals). A Healthy Eating Index evaluated maternal diet quality based on adherence to Danish official dietary guidelines. Offspring with pediatric-onset IBD (≤18 years) were identified in national patient registries. Cox regression explored associations of maternal organic food consumption and diet quality during pregnancy with offspring's risk of pediatric-onset IBD, CD, and UC. Results: The study included 60,274 singleton mother-child pairs, of which 168 children developed pediatric-onset IBD. Frequent maternal organic food consumption during pregnancy was not significantly associated with offspring's IBD risk (HR: 0.63; 95% CI: 0.33-1.19). However, frequent organic food consumption during pregnancy, particularly organic eggs and dairy, lowered offspring's risk of CD (HR: 0.40; 95% CI: 0.17-0.94), but not UC (HR: 1.11; 95% CI: 0.41-3.00). Maternal diet quality during pregnancy was not significantly associated with offspring's risk of IBD (HR: 0.99; 95% CI: 0.97-1.01), CD, and UC. Conclusion: In this large prospective cohort study, we show that maternal organic food consumption, particularly eggs and dairy, during pregnancy may lower offspring's risk of pediatric-onset CD, but not UC.
