Seizures in congenital heart disease: risks, outcomes, and birth cohort data from China.
Article in Frontiers in 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
Objective: Congenital heart disease is the most common birth defect and carries a high risk of seizures; however, specific risk factors and long-term neurodevelopmental outcomes remain poorly defined. We aimed to identify factors associated with seizure occurrence and evaluate neurodevelopmental outcomes in children with congenital heart disease. Methods: This prospective cohort study included 31,734 singleton live births in Lanzhou, China (2018-2023) followed for 18 months. Maternal, demographic, and clinical data were prospectively collected. Congenital heart disease phenotypes were classified as left-to-right shunt, cyanotic, left-sided, or single-ventricle lesions. Univariate logistic regression was conducted to identify factors associated with clinical seizures, and electroclinical and neurodevelopmental profiles were systematically evaluated. Results: Congenital heart disease was diagnosed in 392 infants (1.2%), of whom 23 (5.9%) experienced clinical seizures. Lower birthweight, prolonged hospitalization, and extracorporeal membrane oxygenation support were significantly associated with seizure occurrence (all Conclusions: Seizures represent a critical complication in infants with congenital heart disease, particularly those with single-ventricle physiology or requiring prolonged hospitalization or mechanical circulatory support. Seizure development was associated with poorer 18-month neurodevelopmental outcomes, underscoring the need for proactive neurological surveillance and larger multicenter studies to identify independent risk pathways.
