Multiple PCI Failures Due to Excessive Coronary Hinge Motion.
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
backgroundExcessive vessel movement due to hinge motion (HM) may be one of the major contributors to in-stent thrombosis and subsequent stent fractures. CASE SUMMARY: A 53-year-old man was admitted due to an acute myocardial infarction. Emergency angiography revealed thrombotic right coronary artery occlusion associated with excessive HM. After stenting, he was readmitted for in-stent thrombosis, and in-stent total occlusion and stent fractures were observed at 1-year follow-up; the stent fracture site is precisely located at the HM. Considering the persistent severe HM, coronary artery bypass grafting was recommended. DISCUSSION: Chronic mechanical stress due to HM of the vessel may play an important role in stent fracture. Stent implantation should be avoided in coronary regions with curves due to severe HM. Shorter stent, drug-coated balloons, or coronary artery bypass grafting should be prioritized. TAKE-HOME MESSAGES: Stent implantation should be avoided in regions with severe HM. Shorter stents, drug-coated balloons, or coronary artery bypass grafting should be considered.
