1 · What the graph read from it

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.

2 · The registry

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

Schwannomas are benign tumours arising from Schwann cells in the peripheral nerve. The schwannoma of the accessory nerve is a very rare entity. We report a case of Schwannoma of the extracranial accessory nerve. A 22-year-old man presented with a slow-growing mass, located on the right upper neck. The patient did not have any neurological deficit. CT scan showed a hypodense mass behind sternocleidomastoid muscle. The suspected diagnosis was an adenopathy of the accessory spinal chain. Surgery was done via transcervical approach. The histopathological analysis concluded with a diagnosis of schwannoma. No recurrence was noted at the follow-up examination 29 months after surgery.
