Long-standing inferior vena cava filter with multidirectional strut penetration: A case report.
Article in Radiology case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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) filter penetration is an increasingly recognized complication, particularly after prolonged dwell time or failed retrieval. Although often asymptomatic, multidirectional penetration into adjacent structures may pose a significant risk. We report a 61-year-old man presenting with non-traumatic radicular back pain whose CT imaging demonstrated a retrievable IVC filter placed nine years earlier with extensive strut penetration into the L3 vertebral body, perivertebral soft tissues, bowel loops, distal abdominal aorta, and right mesocolon, along with one fractured strut. Prior retrieval attempts had failed due to filter tilt and hook embedding, without evidence of hemorrhage or retroperitoneal leakage. The patient was referred for complex endovascular retrieval. This case underscores the importance of structured surveillance, timely retrieval, and specialized multidisciplinary management to prevent severe delayed complications.
