Left atrial appendage occlusion with Watchman device after incomplete surgical ligation.
Article in BMJ case reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Non-valvular atrial fibrillation (NVAF) is the most common cause of cardioembolic stroke. The left atrial appendage (LAA) is the major source of cardiac emboli in patients with NVAF. Anticoagulation (AC) is the standard of care for stroke prevention in atrial fibrillation (AF), but many patients are intolerant of AC. Surgical exclusion of the LAA may result in incomplete closure and is associated with an increased risk of embolism. We report a case of a woman in her 50s with a history of persistent AF, mitral valve prolapse s/p repair with surgical LAA exclusion, and multifocal haemorrhagic stroke presented for elective LAA closure who underwent a Watchman placement successfully. This case demonstrates that a percutaneous approach for occlusion of the LAA when surgical exclusion was incomplete may be feasible with appropriate planning. Clinical outcome data for this patient group are needed.
