Timing of Critical Congenital Heart Defect Detection: A Multisite Population-Based Study.
Article in The Journal of pediatrics, 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
objectiveTo evaluate prevalence of and characteristics associated with prenatal and late critical congenital heart defect (CCHD) detection among infants. STUDY
designInfants with CCHD born during 2014-2021 with interviewed mothers were included from the Birth Defects Study To Evaluate Pregnancy exposureS, a multisite, population-based case-control study. Timing of detection was based on date of earliest fetal or postnatal echocardiogram: prenatal, timely postnatal (0-3 days after birth), and late (>3 days after birth). Unadjusted log-linear models evaluated trends in timing of CCHD detection by birth year. Multivariable log-binomial models calculated adjusted prevalence ratios for prenatal and late CCHD detection by demographic and clinical characteristics.
resultsThere were 996 liveborn infants with CCHD included in this analysis. Prenatal detection increased from 2014 (25.0%) to 2021 (39.1%; P for trend = .01). The prevalence of late detection was 22.7% in 2014 and 16.4% in 2021; P = .06. Almost half (48.6%) of infants had timely postnatal detection. Prenatal detection was 1.2 times (95% CI 1.1-1.5) more likely among infants with extracardiac compared with isolated defects. Late CCHD detection was 2.0 times (95% CI 1.2-3.4) more common among infants whose mothers lacked prenatal insurance compared with those with prenatal insurance.
conclusionsDisparities in timing of CCHD detection exist by defect characteristics and insurance. Implementation of improved prenatal detection methods to detect more defect types and interventions to increase access to prenatal care may further improve earlier CCHD detection.
