1 · What the graph read from it

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.

2 · The registry

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 artery fistulas (CAFs) are rare coronary anomalies. Among these, coronary artery-pulmonary artery fistulas can lead to myocardial ischemia through mechanisms such as coronary steal, stenosis, and vasospasm. We report a case of a 73-year-old male presenting with a coronary artery-pulmonary artery fistula and 75% stenosis of the right coronary artery. Despite negative findings for ischemia on myocardial scintigraphy and the absence of ST changes on a resting electrocardiogram (ECG), coronary steal syndrome was suspected following an exercise ECG that revealed diffuse ST depression. Surgical intervention to close the fistula was performed; however, the patient experienced intraoperative coronary spasms and ventricular fibrillation, necessitating the use of intra-aortic balloon pump and veno-arterial extracorporeal membrane oxygenation. The present case suggested that CAFs can be complicated by vasospasm, which may be overlooked at preoperative diagnostics. In patients with CAFs, careful evaluation regarding vasospastic angina should be done preoperatively.
