Persistent Impairment of Coronary Microvascular Dysfunction After Percutaneous Coronary Intervention in an Ice Swimming Champion.
Article in Journal of medical cases, 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
Coronary microvascular dysfunction (CMD) is a recognized cause of persistent angina post-percutaneous coronary intervention (PCI), especially in patients without epicardial coronary stenosis. We report a case of a 58-year-old top-level sportsman and world champion ice swimmer with persistent dyspnea despite successful PCI for a mid-left anterior descending artery lesion. Follow-up angiography with optical coherence tomography showed no in-stent restenosis with good stent apposition. Angiography-derived microcirculatory resistance (AMR, Pulse Medical) and cardiac magnetic resonance imaging revealed CMD as the underlying etiology. This case demonstrates the utility and feasibility of AMR in identifying CMD post-PCI and supports its use in the diagnostic workup.
