Hypertrophic cardiomyopathy in identical twins: a case series.
Article in European heart journal. Case reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background: Hypertrophic cardiomyopathy in identical twins is rare. Cases of hypertrophic cardiomyopathy with homogenous and heterogeneous phenotypes have been described in the literature. Case summary: We report a pair of monozygotic twins (Twin A and Twin B) with identical morphological expression of hypertrophic cardiomyopathy. On initial evaluation, both twins had resting left ventricular outflow tract obstruction, Grade II diastolic dysfunction, and New York Heart Association (NYHA) Class II symptoms, but they had a different clinical course afterward. Twin A progressed from NYHA Class II to Class III with a high left ventricular outflow tract pressure gradient that was unresponsive to medical treatment and required alcohol septal ablation. Twin B responded very well to medical treatment. Both patients had no risk factors for sudden cardiac death, and neither required an implantable cardioverter defibrillator. Discussion: The morphology of hypertrophic cardiomyopathy has a strong genetic basis, but epigenetic factors may affect disease expression.
