Chronic limb sensory abnormalities caused by retained intraspinal metallic foreign body: a case report.
Article in Frontiers in medicine, 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
Intraspinal foreign body retention is a rare clinical entity, usually resulting from trauma, surgery, or invasive procedures, and may lead to progressive neurological dysfunction. We report a patient who presented with burning pain in the right sole and bilateral lower limb weakness, and was diagnosed with a retained metallic foreign body in the thoracic spinal canal by imaging examinations. We discuss the clinical features, imaging diagnosis, and surgical management based on the diagnostic and therapeutic process of this case. This report indicates that invasive therapies such as acupuncture carry the potential risk of needle breakage, migration, and subsequent intraspinal foreign body retention, which deserves clinical attention. Strict standard operation during acupuncture is crucial to avoid such iatrogenic complications.
