Anti-VGLUT2 autoantibodies associated with post-COVID neurocognitive dysfunction: a case report.
Article in Frontiers in immunology, 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
Post-COVID-19 syndrome (PCS) is frequently associated with fatigue and cognitive dysfunction, while underlying mechanisms remain unclear. We report a 44-year-old male with persistent symptoms following SARS-CoV-2 infection, including severe cognitive and motor fatigue, word-finding difficulties, and impaired concentration. Neuropsychological testing revealed marked deficits in alertness, attention, fluency, and processing speed. Serum analysis demonstrated anti-VGLUT2 autoantibodies. IVIG therapy yielded subjective but no objective improvement. This appears to be the first PCS case associated with VGLUT2 autoantibodies and raises the hypothesis of a potential pathophysiological link that requires confirmation in larger cohorts.
