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: This case highlights a type 4 dual left anterior descending coronary artery anomaly, identified incidentally during coronary angiography. Case summary: A 51-year-old male patient presented with acute myocardial infarction, which was successfully treated with thrombolysis and percutaneous coronary intervention. Angiography revealed an anomalous origin of the left anterior descending artery (LAD) from the right coronary artery. Stenting was performed on the right coronary artery and the right posterior descending artery branch. Discussion: Type 4 dual LAD is a rare coronary anomaly with potential clinical risks, including sudden cardiac death due to its course between major arteries. Variations in the structure of coronary arteries can present challenges for interventional cardiologists when conducting percutaneous coronary interventions. Accurate coronary anatomy assessment via angiography and computed tomography coronary angiography is crucial for successful percutaneous coronary intervention and surgical planning. Although uncommon, the dual LAD type 4 anomaly is a significant coronary artery variation that interventional cardiologists must consider due to its impact on prognosis and long-term treatment strategies.
