Maternal Risk Factors for Omphalocele.
Article in Fetal diagnosis and therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionOmphalocele is a rare congenital abdominal wall defect characterized by the herniation of abdominal organs through the umbilical ring, covered by a protecting sac. The etiology is not fully understood, and little is known about the role of maternal factors. The aim of this study was to investigate the role of maternal risk factors in the development of omphalocele.
methodsA population-based case-control study was conducted using data from Swedish national registries between 1997 and 2016. The study included 207 mothers of children born with omphalocele (cases) and 2,070 controls, matched on the children's sex and birth year. Conditional logistic regression analysis was used to estimate odds ratios (OR) with 95% confidence intervals (CI).
resultsMaternal obesity (adjusted OR: 1.82, 95% CI: 1.14-2.88) and IVF conception (adjusted OR: 4.49, 95% CI: 1.76-11.4) were associated with an increased risk of omphalocele. Multiparity was associated to decreased risk (adjusted OR: 0.44, 95% CI: 0.25-0.77) as 58% of the omphalocele cases were firstborn.
conclusionsMaternal obesity and IVF conception are factors associated with an increased risk of omphalocele, whereas multiparity is linked to decreased risk.
