Duraplasty with laminoplasty for Hirayama disease: a technical note with a case series.
Article in Asian spine journal, 2025. 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
Hirayama disease, a form of cervical myelopathy predominantly affecting young males, is characterized primarily by distal muscle atrophy in the upper limbs. We investigated the surgical outcomes of duraplasty with laminoplasty for Hirayama disease. Five male patients with an average age of 17.4 years with Hirayama disease who had preoperative muscle atrophy and numbness in the upper extremities underwent duraplasty with laminoplasty. The severity of disability in activities of daily living was classified using the Tokumaru classification. Following cervical duraplasty with laminoplasty, all patients experienced significantly improved upper extremity performance. Hirayama disease is characterized by an inelastic dura that constricts and compresses the cervical spinal cord when the neck is flexed. Duraplasty with laminoplasty is proposed as an effective treatment for Hirayama disease.
