Safety and efficacy of a novel biodegradable occluder- Pansy ® occluder compared with traditional nondegradable occluder in the closure of patent foramen ovale.

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
Background: Traditional nondegradable patent foramen ovale (PFO) occluders pose mechanical complications and may limit potential transseptal access, necessitating biodegradable alternatives without permanent implants. The safety and efficacy of the fully biodegradable Pansy® occluder have not been directly compared with traditional nondegradable devices. Objects: To compare the Pansy® occluder with traditional nondegradable occluders for percutaneous closure of PFO, focusing on complications, adverse events, and closure outcomes during follow-up. Methods: We retrospectively analyzed consecutive patients who underwent PFO closure with the Pansy® occluder ( Results: Before matching, Pansy® recipients were younger and included fewer female patients. After matching, baseline characteristics were well balanced. Procedural success was 100% in both groups, with no severe adverse events. Device-related thrombosis occurred in three patients in the Pansy® group (6.82% vs. 0.00%, Conclusions: The Pansy® occluder demonstrated comparable safety and efficacy compared to nondegradable devices for PFO closure.
