Endovascular retrieval of Greenfield IVC filters 13 and 19 years post placement without major complication.
Article in Journal of radiology case reports, 2017. 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
Inferior vena cava (IVC) filters were first introduced in 1967 by Kazi Mobin-Uddin and later improved by Lazar Greenfield in the 1980s becoming a major component of catastrophic pulmonary embolism prevention. Nevertheless, filters are not entirely harmless. The long term risks include caval thrombosis, visceral penetration, and filters can serve as a nidus for infection. Filter retrieval is often complicated by intimal hyperplasia especially with increased indwelling time. Historically, Greenfield filters in place for longer than 3 weeks were considered permanent due to the risks of retrieval. Herein we present 2 cases of successful retrieval of Greenfield filters 13 and 19 years post implantation.
