A Tale of Two LADs (Left Anterior Descending Arteries): Type IV LAD as a Rare Coronary Anomaly.
Article in Cureus, 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
A dual left anterior descending (LAD) artery is angiographically defined as the presence of two distinct coronary arteries supplying the LAD territory. It represents a rare coronary artery anomaly in the general population but may have important implications during the evaluation and management of acute coronary syndromes (ACS), percutaneous coronary intervention (PCI), and coronary artery bypass grafting (CABG). Accurate recognition of this variant is essential to avoid misinterpretation of coronary angiograms, incomplete revascularisation, and procedural complications. The objective of this case report is to describe the clinical presentation, angiographic characteristics, and management of two patients diagnosed with type IV dual LAD anomaly in the setting of ACS, one presenting with ST-elevation anterior wall myocardial infarction (STEMI) and the other with non-ST-elevation myocardial infarction (NSTEMI). The report also aims to highlight key diagnostic clues and practical considerations for interventional cardiologists and cardiac surgeons when encountering this rare anomaly.
