Indirect Confirmation of a COVID-19 Encephalitis Case.
Article in Cureus, 2023. 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
A 58-year-old man was admitted to the hospital with acute neurological manifestations of encephalitis 15 days after a previous upper respiratory COVID-19 illness. On presentation, he was confused with altered mental status, aggressive behavior, and a Glasgow coma scale score of 10/15. Laboratory investigation, brain computed tomography (CT), and brain magnetic resonance imaging (MRI) were unremarkable with normal results. Although the cerebrospinal fluid (CSF) polymerase chain reaction (PCR) for SARS-CoV-2 was negative, we found increased concentrations of positive immunoglobulin (Ig) A and IgG antibodies in CSF, suggesting acute central nervous system (CNS) infection and indirect confirmation of virus neuroinvasion. There was no evidence of humoral auto-reactivity, and we rejected the hypothesis of autoimmune encephalitis with known autoantibodies. On the fifth day of hospitalization, myoclonic jerks emerged as a new neurological sign until the added levetiracetam led to total remission. The patient achieved full recovery after antiviral and corticosteroid therapy implementation of 10 days in the hospital. This case report emphasizes the importance of the presence of CSF IgA and IgG antibodies to diagnose encephalitis in COVID-19 patients as an indirect confirmation of CNS infection.
