Palato-pharyngo-laryngeal myoclonus with recurrent retrograde feeding tube migration after cerebellar hemorrhagic stroke: a case report and review of hypertrophic olivary degeneration.
Article in BMC neurology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundPalato-pharyngo-laryngeal myoclonus, a variant of palatal myoclonus, is characterized by involuntary rhythmic movements of palatal, pharyngeal, and laryngeal muscles. Symptomatic palatal myoclonus is classically associated with hypertrophic olivary degeneration on MRI imaging due to a lesion in the triangle of Guillain-Mollaret. CASE PRESENTATION: We report a case of palato-pharyngo-laryngeal myoclonus in a patient post-cerebellar hemorrhagic stroke who presented with recurrent retrograde migration of his gastrojejunostomy feeding tubes. Treatment with either divalproex sodium or gabapentin resulted in a significant decrease in his gastrointestinal symptoms and no further episodes of gastrojejunostomy tube migration.
conclusionsThis case study indicates that the movement disorder associated with hypertrophic olivary degeneration may involve the gastrointestinal system. Anticonvulsants, such as gabapentin and divalproex sodium, may reduce the severity of gastrointestinal symptoms in cases associated with hypertrophic olivary degeneration. The anatomy of the Guillain-Mollaret triangle and the pathophysiology of hypertrophic olivary degeneration are reviewed.
