Arrhythmogenic Isolated Right Coronary Vasospasm.
Article in JACC. Case reports, 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
backgroundCoronary vasomotion disorders, although prevalent among patients with ischemia, remain poorly understood given limited use of invasive functional testing. CASE SUMMARY: Presented here is a case of isolated severe right-coronary-artery vasospasm with acetylcholine reactivity testing resulting in ventricular arrhythmias. DISCUSSION: Determining the type of coronary vasomotion disorder is important for providing the appropriate treatment; therefore, performing invasive functional testing is critical. Although isolated right-coronary-artery vasospasm is rare, if vasospastic angina is of high suspicion, evaluating the right coronary artery is necessary. TAKE-HOME MESSAGES: Vasospastic angina can occur in any phase of coronary atherosclerotic disease and result in myocardial infarction or sudden cardiac death. Vasomotor disorders can involve variable regions and combinations of microvascular and epicardial coronary arteries. A comprehensive diagnosis of vasomotor disorders is only possible with reactivity testing, with isolation of both right and left coronary arteries when indicated.
