Brainstem Encephalitis Following COVID-19 Vaccination: A Case Report.
Article in Cureus, 2026. 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
Encephalitis is an extremely rare neurological adverse event following vaccination against coronavirus disease 2019 (COVID-19). We report a case of brainstem encephalitis following mRNA COVID-19 vaccination. A 30-year-old Japanese female presented with acute diplopia characterized by recurrent, paroxysmal episodes following the second dose of the vaccine, which resolved spontaneously. Brain magnetic resonance imaging revealed inflammatory changes in the brainstem. The patient responded rapidly to steroid therapy and subsequently improved. This case shares key clinical features with another case, including similarities in symptoms, lesion localization, and steroid responsiveness. However, it differs with respect to the timing of symptom onset and the presence of mild residual deficits. This report makes a contribution to the limited literature on this rare post-vaccination condition by documenting its clinical features.
