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
Implantation of a left ventricular assist device in the presence of a pre-existing patent foramen ovale or an iatrogenic atrial septal defect (ASD) may predispose patients to significant right-to-left shunting, resulting in critical hypoxaemia. In such cases, the appropriate treatment modality has been intervention with transoesophageal echocardiography-guided ASD closure using fluoroscopy. ASD closure without fluoroscopy to reduce radiation exposure has been discussed but not properly explored. We present a case of a 72-year-old patient with a history of left ventricular assist device placement complicated by critical hypoxaemia secondary to a large residual ASD who underwent emergency bedside treatment using transoesophageal echocardiography without fluoroscopy. Although ASD closure without fluoroscopy is not well established, this case highlights a novel technique to promptly and successfully treat critical hypoxaemia in patients with significant shunting.
