Dynamic Ultrasound Imaging of Extensor Pollicis Brevis Hypertrophy in Proximal Intersection Syndrome: A Case Report and Literature Review.
Review in Journal of clinical ultrasound : JCU, 2026. 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
This case report presents an atypical presentation of proximal intersection syndrome and provides ultrasound-based evidence of extensor pollicis brevis muscle belly hypertrophy with associated edema in a non-athletic population. While occupationally induced PIS has been previously documented, the patient's symptoms in this case were linked to repetitive lifting tasks involving prolonged extension of the first metacarpophalangeal joint with a wide grip. Dynamic ultrasound assessment revealed radial displacement of the second compartment tendons by the extensor pollicis brevis muscle during the aggravating movement. This finding suggests a novel pathomechanism, potentially driven by mechanical friction and stress between the first and second dorsal compartments, warranting further investigation.
