An Atypical "Hot-Phase" ARVC in a PKP2 Carrier.
Article in JACC. Case reports, 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
backgroundArrhythmogenic right ventricular cardiomyopathy (ARVC) is a leading inherited cause of sudden cardiac death in young athletes. Rarely, ARVC may present with acute myocardial injury and troponin elevation, mimicking myocarditis and delaying diagnosis. CASE SUMMARY: A 20-year-old competitive female cross-country runner presented with exertional presyncope and emesis during a race and was found to have marked troponin elevation. Electrocardiography demonstrated T-wave inversions in leads V DISCUSSION: This case represents an atypical "hot-phase" presentation of PKP2-mediated ARVC with isolated right ventricular involvement and myocardial injury, distinct from the more common DSP-associated left-dominant phenotype. TAKE-HOME MESSAGES: ARVC should be considered in young athletes presenting with exertional syncope and troponin elevation. Cardiac magnetic resonance is critical for distinguishing ARVC from myocarditis.
