1 · What the graph read from it

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.

2 · The registry

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

Transcatheter left atrial appendage closure (LAAC) serves as a mechanical stroke prevention strategy for patients with non-valvular atrial fibrillation (NVAF) who are unsuitable for long-term oral anticoagulation. Although device dislodgement following LAAC is rare, it carries potentially life-threatening risks. This case report describes a 65-year-old male with permanent atrial fibrillation (CHA2DS2-VASc = 4, HAS-BLED = 3) who underwent LAAC with an 18 mm LAmbre occluder. Despite confirmed proper positioning at 1-month follow-up, device migration to the iliac bifurcation was detected at 105 days post-procedure, potentially associated with interim chest trauma. Percutaneous retrieval was performed via a novel approach: catheter-based endothelial detachment followed by bidirectional traction, avoiding large-bore sheaths. A Watchman FLX device was subsequently implanted successfully.
