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
objectiveDevice-related thrombus (DRT) is a life-threatening complication of left atrial appendage closure devices. Transcatheter vacuum-assisted thrombectomy has recently been described as a novel strategy for removal of large DRT, but it is associated with increased risk of systemic embolism. We describe a step-by-step technique of a complete embolic protection strategy in patients undergoing vacuum-assisted thrombectomy. KEY STEPS: First, bilateral cerebral embolic protection devices are deployed. Next, systemic embolic protection is achieved by positioning an ONO retrieval device (Onocor) within the proximal aortic arch. An arterial return cannula is inserted. Then, transseptal crossing is performed with positioning of a suction catheter within the left atrium for aspiration thrombectomy. POTENTIAL PITFALLS: Aspiration should be performed meticulously, avoiding traumatic dislodgment of thrombotic material. The ONO basket must be assessed for embolic debris before its removal using transesophageal echocardiography. Long-term oral anticoagulation should be considered if tolerated. TAKE-HOME MESSAGE: Transseptal transcatheter vacuum-assisted thrombectomy with complete embolic protection is a viable and effective strategy to prevent thromboembolic complications for life-threatening DRT.
