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
Collateralisation around stenotic or occlusive arterial disease is a commonly observed adaptation for maintenance of arterial perfusion. It occurs through pathways of well-understood embryological origin. Examples include Winslow's pathway (internal thoracic artery to iliac artery via the epigastric arteries) and the arc of Riolan (between superior and inferior mesenteric arteries). In this article, we describe a pathway of collateralisation around stenotic disease of the coeliac and superior mesenteric arteries in a 76-year-old man with an abdominal aortic aneurysm. The collateral pathway was identified on computed tomography angiography between the left internal thoracic artery in the thorax and the coeliac artery in the abdomen via the left inferior phrenic artery. This has implications for routine cardiac surgery, such that left internal thoracic artery harvest during coronary artery bypass surgery would likely result in acute ischaemia of the abdominal viscera.
