Supernumerary extensor pollicis longus tendon masking an extensor pollicis longus rupture following non-surgical treatment of a distal radius fracture.
Article in BMJ case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Extensor pollicis longus tendon pathology is a recognised complication following non-surgical treatment of non-displaced distal radius fractures. Tendon entrapment typically presents with pain, but preservation of thumb retropulsion during complete rupture results in loss of active thumb retropulsion and tenodesis effect. We present the case of a 52-year-old woman who developed extensor pollicis longus tendon entrapment with full active thumb extension following a non-displaced distal radius fracture. During her elective third dorsal compartment release, the extensor pollicis longus tendon was found to be completely ruptured and a rare supernumerary extensor pollicis longus tendon was found emerging from the fourth dorsal compartment. Gentle traction of this tendon resulted in thumb interphalangeal joint extension and simultaneous index finger metacarpophalangeal joint extension. An extensor indicis proprius to extensor pollicis longus tendon transfer was performed. At her final 6-month follow-up, she had painless full active thumb motion comparable to her contralateral side.
