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

A 69-year-old man presented with recurrent vertigo triggered by positional changes, left aural fullness, and left hemifacial spasm. The supine roll test showed direction-changing apogeotropic horizontal nystagmus lasting < 1 min. Brain MRI demonstrated neurovascular contact between the cranial nerve VII/VIII complex and the anterior inferior cerebellar artery. Carbamazepine 200 mg/day achieved complete symptom resolution within 2 weeks and remission at 6 months. This report describes vestibular paroxysmia presenting with nystagmus resembling that observed in benign paroxysmal positional vertigo and, to our knowledge, represents the first report of direction-changing apogeotropic horizontal nystagmus in this disorder.
