Prenatal detection and outcome of major heart defects in a country with universal screening.

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
objectiveTo evaluate the Danish prenatal screening program for major fetal congenital heart defects (mCHD), focusing on incidence, detection rates (DRs), pregnancy outcomes and postnatal mortality.
methodsThis was a 5-year nationwide cohort study conducted from January 2018 to December 2022 in Denmark. We included pregnancies suspected of and/or with a confirmed mCHD and children with a confirmed mCHD, and excluded those who were not screened, false-positive cases and those who emigrated before delivery. The main outcome was the prenatal DR of mCHD. Secondary outcomes were rate of termination of pregnancy, liveborn incidence of mCHD, gestational age at delivery, neonatal surgery rate and postnatal mortality.
resultsData from a total of 645 pregnancies and children with mCHD were retrieved from local databases and 602 were included in the final analysis. The prenatal DR of mCHD was 82.6% (497/602), with one of the highest DRs observed for univentricular heart (99.4% (159/160)) and the lowest DR for total anomalous pulmonary venous return (7.7% (1/13)). Termination of pregnancy occurred in 43.4% (261/602) of cases, with 52.5% (261/497) of prenatally detected cases opting for termination. The liveborn incidence of mCHD was 0.11% (1.1 per 1000 births), and the median gestational age at delivery was 39 + 2 weeks. Surgery was performed in 92.0% (300/326) of liveborn children, primarily within the first month after birth. The postnatal follow-up time was between 8 months and 5 years, with a mortality rate of 9.8% (32/326), of which 50.0% occurred neonatally without surgery.
conclusionsThis study highlights increased prenatal DRs and a declining liveborn incidence of mCHD in Denmark, underscoring the efficacy of the national screening program and centralized care. Furthermore, the vast majority of patients were treated surgically, and the mortality rate was low. The declining liveborn incidence of mCHD should be monitored and potential causes explored further. © 2025 The Author(s).
