Sudden hemichorea and frontal lobe syndrome: a rare presentation of unbalanced polycythaemia vera.
Article in BMJ case reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Polycythaemia vera (PV) is an haematological neoplasm that frequently presents neurological symptoms. However, chorea is a rare complication of this disease, occurring in less than 5% of the patients. Cognitive impairment related to PV unbalanced is also a rare complication, and it can improve with proper treatment. We present a 96-year-old-man with acute-onset hemichorea and frontal lobe syndrome with no vascular pathology in the basal ganglia or frontal region. A clear relationship was observed between the onset of involuntary movements and the cognitive impairment and worsening of haematological parameters in the patient. After causal and symptomatic treatment, the patient's clinical status improved. In the elderly, PV must be considered as a cause of acute chorea and sudden cognitive impairment, as early diagnosis leads to effective treatment and prevention of complications.
