[Factors Contributing to Inferior Vena Cava Filter Removal Failure using Advanced Techniques: A Single-Center Study].

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
Purpose: To investigate the factors contributing to inferior vena cava (IVC) filter removal failure by comparing successful and failed cases using advanced techniques. Materials and Methods: IVC filter removal was attempted in 331 patients. Of the 29 patients in whom IVC filter removal failed using a simple technique, the IVC filter was successfully removed using an advanced technique in 18 patients and failure was noted in 11 patients. Age, sex, filter type, indwelling period, IVC diameter, tilting angle between the IVC and the filter, IVC wall penetration of the filter strut, and whether the filter was embedded or endothelialized within the IVC wall were compared in each group. Results: Overall, there were 13 men (72%) in the success group and 3 men (27%) in the failure group; more women were present in the failure group ( Conclusion: When using advanced techniques for IVC filter removal, females are at a higher risk of failure compared to males. Hook embedment and IVC filter endothelialization within the IVC wall, rather than penetration of the IVC wall, are crucial factors in failure of IVC filter removal using advanced techniques.
