Recurrent Positional Vomiting due to Cerebellar Infarction and Obstructive Hydrocephalus.

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
An 80-year-old woman presented with the sudden onset of vertigo and vomiting and was diagnosed with acute cerebellar infarction. Twelve days after the onset, she experienced positional vomiting, predominantly in the lying-down position, triggered by postural changes with immediate or delayed onset. Over 1 month, 23 episodes of vomiting occurred. Brain computed tomography revealed edema in the infarcted area, fourth ventricular outlet compression, and lateral ventricular enlargement. These findings suggest that fluctuations in intracranial pressure are associated with intermittent obstructive hydrocephalus exacerbated by the patient's posture. This case highlights the importance of considering postural triggers in patients with recurrent vomiting associated with cerebellar infarctions.
