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
Objective: To evaluate the safety and feasibility of the "filter-thrombus integrated retrieval technique," which leverages the controllable deformation characteristics of spindle-shaped inferior vena cava (IVC) filters, for the retrieval of filters with thrombus burden. Methods: A retrospective analysis was conducted on clinical data from 51 patients with IVC filter thrombosis (IVCFT) treated at our center from September 2023 to September 2025. All patients underwent retrieval using the "filter-thrombus integrated retrieval technique" to construct a "filter-thrombus complex" for Results: The mean filter dwell time was 35.25 ± 5.80 days. 3D measurements revealed a mean thrombus volume of 4.60 ± 0.42 cm Conclusion: The filter-thrombus integrated retrieval technique appears to be a safe and feasible strategy for managing thrombosed filters. Through a unique physical "caging" mechanism, this technique minimizes the risk of iatrogenic PE during retrieval without relying on additional thrombolysis or aspiration devices. It presents a viable option for patients with high thrombus burden or contraindications to anticoagulation.
