Paroxysmal kinesigenic dyskinesia: a diagnostic challenge.
Article in BMJ case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
A 10-year-old girl presented with a month long history of episodic limb movements. She had a normal neurological examination and after thorough investigation, she was thought to have possible tics. Anxiety was reported as being a trigger. Unusually, these 'tics' were not directly witnessed during hospital visits. Eighteen months after the initial presentation, the clinician observed dystonic posturing after the child stood up from having been seated during a consultation. Paroxysmal kinesigenic dyskinesia (PKD) was then suspected and confirmed on genetic testing. She was successfully treated with carbamazepine. In hindsight, it became apparent that her anxiety was related to a fear of uncontrolled movements, rather than it being a trigger. The abnormal involuntary movements in PKD are precipitated by sudden voluntary movement. Lack of recognition of this typical feature, normal examination and/or features such as coexisting anxiety can lead to misdiagnosis or delayed diagnosis of this easily treatable condition.
