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
A 75-year-old woman with a history of intracranial haemorrhage, atrial fibrillation and coronary artery bypass graft underwent elective left atrial appendage occlusion (LAAO) for stroke prevention. The procedure was successful, however on the third postoperative day, she presented with a lymph leak at the right femoral venous access site. She was admitted for conservative management of the lymph leak with immobility and intravenous fluids. Her inpatient stay was complicated by a right lower limb deep vein thrombosis (DVT), left middle cerebral artery territory ischaemic stroke, pulmonary emboli (PEs) and a splenic infarction. The mechanism of the systemic emboli was that of paradoxical emboli from the DVT passing through an interatrial septal defect created as part of the LAAO procedure, a previously unreported complication of LAAO. She was managed with 6 months of low-dose oral anticoagulation for treatment of DVT and PE and has made a full neurological recovery.
