Elucidation of the clinical traits of diabetic chorea through a questionnaire survey of people with diabetic chorea from 59 Japanese hospitals.

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
aimsDiabetic chorea refers to sudden involuntary movements developing in people with diabetes mellitus and is known to occur mainly in those with severe hyperglycemia. We conducted a questionnaire survey of case-reporting facilities in Japan to elucidate their clinical characteristics.
methodsWe searched the PubMed and Ichushi databases for case reports published from January 1, 2012, to December 31, 2017, using "diabetes" and "chorea" as keywords, and sent a questionnaire to the reporting institutions.
resultsData from a total of 64 cases were included in this study. While most cases had severe hyperglycemia at the onset of diabetic chorea, hypoglycemia/improvement of the plasma glucose served as the trigger for the symptom in 14 cases (21.9%). The Early Remission Group (≤6 months) consisted of 39 cases (60.9%), while the Prolonged Partial Remission Group (>6 months) included 25 cases (39.1%). In the Prolonged Partial Remission Group (>6 months), there were more cases with widespread involuntary movement symptoms, a higher number of cases exhibiting typical imaging findings, and a greater incidence of chorea onset after the initiation of antidiabetic treatment, including hypoglycemia.
conclusionsMost reported cases of diabetic chorea in Japan were elderly persons with type 2 diabetes mellitus and severe hyperglycemia, although there were also some cases in which the symptom developed in the setting of hypoglycemia. It has been suggested that rapid plasma glucose correction and hypoglycemia might be associated with the risk of development and prognosis of diabetic chorea.
