Radial Support Force: A Key Player in Vena Cava Neointimal Hyperplasia.
Article in Journal of inflammation research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Neointimal hyperplasia (NIH) is a risk factor for inferior vena cava filter (IVCF) retrieval failures and damage to the inferior vena cava (IVC) wall post-retrieval. Unfortunately, the mechanical properties of IVCFs have not been evaluated and are not readily available from the manufacturer. This study aimed to investigate the correlations between radial support force (RSF) and NIH, and the release of tumor necrosis factor-alpha (TNF-α) during this process. Methods: RSFs exerted by IVCF struts at various IVC diameters were analyzed with five replicates in vitro. In vivo, Bama swine were randomly fitted with IVCFs of 32 mm or 20 mm diameter. After a dwelling time of three weeks, the thickness of NIH and TNF-α content in the areas adjacent to IVCF struts were determined on hematoxylin and eosin. Correlations were assessed using Student's Results: A mismatch between IVC and IVCF diameter generated an oversizing ratio (OR), with a mean OR of 113.06 ± 48.91% (range, 61.73-166.52%). RSFs of 4.56 ± 0.97 N (range, 3.54-5.61 N) showed a linear dose-response relationship with ORs ( Conclusion: Differences in RSFs are consistent with ORs; RSFs increased with the larger ORs of IVCF and IVC diameter. Increased RSFs correlate with greater NIH thickness. Evaluation of IVCF yielded a significantly higher RSF at a smaller caval diameter, with higher levels of TNF-α during expansion, supporting a close association with greater NIH.
