Diaphragmatic myoclonus post cerebellar hemorrhage: a case report.
Article in BMC neurology, 2024. 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
backgroundDiaphragmatic myoclonus is a rare motor disorder that affects muscle tone. It is characterized by involuntary movements of the abdominal wall and rhythmic, repetitive contractions of the accessory or respiratory muscles, all of which are innervated by the cervical nerve roots. CASE DESCRIPTION: We reviewed the case of a 57-year-old male patient who underwent surgery for a left cerebellar hemorrhage. He exhibited persistent myoclonus in the palate, jaw, and thoracoabdominal region. Following treatment, there was a significant reduction in flutter amplitude in these areas.
conclusionThe clinical rarity and variability of presentations often make diagnosis challenging and delayed. It is believed that this condition stems from abnormal excitation within the central nervous system or neural pathways that involve the phrenic nerve. Another potential mechanism is the direct irritation of the diaphragm. Ultrasound, chest fluoroscopy, and electromyography (EMG) can support the diagnosis. Various pharmacological and surgical treatments have been tried, yet specific treatment guidelines are still lacking.
