COVID-19 vaccine-induced parkinsonism due to LGI1 antibody encephalitis: case report and brief literature review.
Article in Oxford medical case reports, 2025. 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
Anti-LGI1 encephalitis is an autoimmune disorder of the brain, characterized by subacute cognitive impairment, faciobrachial dystonic seizures, and hyponatremia. Although rare, recent reports suggest that LGI1 encephalitis may be triggered following COVID-19 exposure whether through infection or vaccination. It usually presents with insidious progression which, along with old age predominance, may delay the diagnosis. We herein report a 67-year-old patient with positive LGI1 antibody titers, who developed subacute parkinsonism after serial COVID-19 vaccination. To our knowledge, this is the first documented case report highlighting a potential association between COVID-19 vaccination and the development of parkinsonism in the context of LGI1 encephalitis.
