Exercise testing in athletes: an adjunct to diagnose arrhythmogenic cardiomyopathy?
Article in Frontiers in cardiovascular medicine, 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
Differentiating physiological adaptation to exercise from cardiomyopathic hearts can be challenging. Specifically, evidence of how to deal with athletes under suspicion of arrhythmogenic cardiomyopathy (ACM) but not fulfilling diagnostic criteria is scarce and necessitates a better understanding of exercise pathophysiology and prospective trials. Upon available literature, we discuss and suggest research on combined stress echocardiography and cardiopulmonary exercise testing (CPET echocardiography) to demonstrate mismatch between cardiac output and metabolic demand. Integrating CPET echocardiography in suspected ACM cases may be feasible and could help to better differentiate physiological adaptation to exercise from cardiomyopathic hearts and may become a valuable adjunct for risk stratification and diagnostic frameworks. Future studies should implement combined CPET and stress echocardiography to differentiate physiological adaptations to exercise from cardiomyopathies in athletes with suspected ACM not fulfilling diagnostic criteria.
