Omphalocele prevalence and co-occurring malformations: a nationwide register-based study of Danish live births in 1997-2021.
Article in Pediatric surgery international, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeOmphalocele is a congenital abdominal wall defect associated with a high risk of morbidity and mortality, with co-occurring congenital malformations often being the most important prognostic factor. High rates of spontaneous and medical terminations have been reported among pregnancies with omphalocele and co-occurring malformations. Few studies have focused on co-occurring malformations, particularly non-gastrointestinal malformations among live births. This study examined birth prevalence of omphalocele and co-occurring major malformations among a 25-year Danish liveborn cohort.
methodsThis nationwide retrospective prevalence study used data from the Danish National Patient Register and Danish Civil Registration System for infants who were delivered in Denmark during 1997-2021 and included in the Danish neonatal screening biobank. Diagnoses of omphalocele and co-occurring malformations were ascertained and prevalence estimated using Poisson regression.
resultsAmong 1,498,685 live births, 147 infants with omphalocele were identified, yielding a combined and stable prevalence (per 10,000 infants) of 0.98 (95% CI 0.83-1.15). Over one-half (53.7%) presented with one or more major malformations, and an additional 17.0% were diagnosed with a syndrome.
conclusionsOmphalocele birth prevalence in Denmark was stable over a recent 25-year period. The proportion of infants with co-occurring major malformations or diagnosed syndrome has important implications for long-term healthcare demands.
