Interplay Between Myocardial Bridging, Atherosclerosis, and Spasm in Patients With Nonobstructive Coronary Arteries.
Article in Journal of the Society for Cardiovascular Angiography & Interventions, 2025. 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: Previous evidence suggested individual associations between myocardial bridging (MB), atherosclerosis, and epicardial vasospasm. The complex interplay between these 3 identities has not been well studied in the North American population. Methods: All patients with angina and nonobstructive coronary arteries referred for coronary angiogram who underwent invasive coronary function testing (adenosine and acetylcholine provocation testing) at 2 North American centers between March 2016 and January 2021 were included. The prevalence of epicardial spasm (new >90% stenosis after acetylcholine injection) was assessed according to the presence of MB and moderate atherosclerosis (>50% stenosis or previously stented with negative fractional flow reserve). Results: In total, 472 patients were included, from whom 18.4% (n = 87) had MB and 30.5% (n = 144) had moderate atherosclerosis. The overall prevalence of epicardial spasm was 27.8% (n = 132). Epicardial spasm occurred in 43.7% (n = 38) in patients with MB vs 24.4% (n = 94) in patients without MB ( Conclusions: Epicardial vasospasm occurs most frequently in patients with both MB and moderate atherosclerosis.
