A Case Report of an Atypical Presentation of Morvan Syndrome.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Morvan syndrome, also known as Morvan's fibrillary chorea, is a rare paraneoplastic neurological syndrome presenting with central nervous system (CNS) symptoms, peripheral nerve hyperexcitability, and autonomic nervous system (ANS) manifestations. The etiology and severity of the disease are not well understood. An adult female presented with a sudden onset of chest pain, unilateral extremity weakness, blepharospasms, and muscle spasms, with positive voltage-gated potassium channel (VGKC) antibody and positive neuronal antibody (amphiphysin) in serum. Morvan syndrome can be diagnosed in patients with myokymia, positive VGKC antibody, and neuropsychiatric symptoms with a high clinical index of suspicion. This atypical presentation of Morvan syndrome in a female identifies a novel association of amphiphysin positivity in this rare disease.
