Outcome of contemporary unprotected left main percutaneous coronary intervention in patients with acute myocardial infarction.
Article in Frontiers in cardiovascular medicine, 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
Background: Limited data are available on clinical characteristics and outcomes in patients with culprit or non-culprit left main coronary artery (LMCA) stenosis between ST-segment elevation myocardial infarction (STEMI) and non-STEMI. Methods: This study aimed to compare treatment pattern and outcome between STEMI and non-STEMI according to culprit and non-culprit LMCA stenosis. We examined 572 patients with LMCA stenosis from the Korean Acute Myocardial Infarction Registry-National Institute of Health database. Major adverse cardiac and cerebrovascular events (MACCE) were defined as all-cause death, nonfatal myocardial infarction (MI), repeat revascularization, cerebrovascular accident, rehospitalizations, and stent thrombosis. Results: In patients with culprit LMCA stenosis, cardiogenic shock (50.5% vs. 12.1%; Conclusions: PCI for culprit LMCA stenosis is challenging in both STEMI and non-STEMI despite appropriate mechanical hemodynamic support. Concurrent PCI for non-culprit LMCA stenosis in STEMI does not improve MACCE.
