Similar burden of rare genetic variants in ischemic and non-ischemic dilated cardiomyopathy.
Article in Frontiers in cardiovascular medicine, 2025. 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
Background: The aim of the study was to determine the prevalence of rare disease-causing variants in cardiomyopathy-associated genes in a cohort of patients with ischemic and non-ischemic dilated cardiomyopathy undergoing heart transplant. Methods: We conducted a single-center cohort study of 60 adult patients with left ventricular ejection fraction ≤50% and left ventricular end-diastolic dimension ≥95th percentile for sex/height who underwent heart transplant between January 2017 and December 2023 and consented to participate in a cardiac tissue biobank. We evaluated the prevalence of rare (minor allele frequency <0.1%) disease-causing (pathogenic or likely pathogenic by American College of Genetics and Genomics criteria) variants in cardiomyopathy-associated genes. Results: A total of 60 individuals fulfilled the inclusion criteria: 16 with ischemic dilated cardiomyopathy [88% men, median age 65 years, interquartile range (IQR) 64-68 years] and 44 with non-ischemic dilated cardiomyopathy (80% men, median age 53 years, IQR 39-65 years). We found that the prevalence of disease-causing variants was similar between patients with ischemic dilated cardiomyopathy (3/16 or 19%; 95% credible interval 6%-36%) and those with non-ischemic dilated cardiomyopathy (10/44 or 23%; 95% credible interval 12%-33%). Variants in the ischemic dilated cardiomyopathy group were found in the Conclusions: Patients with ischemic dilated cardiomyopathy undergoing heart transplant possessed a similar burden of rare disease-causing variants as those with non-ischemic dilated cardiomyopathy. Our results suggest that genetic testing may be beneficial in patients with advanced heart failure requiring heart transplant due to ischemic dilated cardiomyopathy to detect disease-causing variants in cardiomyopathy-associated genes.
