Case Report: Recurrent stroke-like episodes triggered by high-altitude exposure in X-linked charcot-marie-tooth disease.

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
X-linked Charcot-Marie-Tooth disease type 1 (CMTX1) is a rare inherited neuropathy caused by mutations in the GJB1 gene, leading to progressive distal muscle weakness and atrophy. In this case study, a 37-year-old man presented with recurrent episodes of numbness involving the lips, right hand, and foot, followed by right-sided limb weakness and dysarthria four times over the past 20 years. Notably, the last three episodes were consistently triggered within 3 days after descent to sea level following exposure to high-altitude environments (8,500-10,000 feet, with transit above 13,000 feet). Based on the neurologic examination, brain magnetic resonance imaging (MRI), and genetic testing, the patient was diagnosed with X-linked Charcot-Marie-Tooth disease. This case underscores the importance of considering high-altitude exposure as a potential trigger and highlights the value of GJB1 testing in young patients presenting with acute stroke-like episodes and signs of peripheral neuropathy.
