Jamestown Canyon virus-mediated meningoencephalitis with unusual laboratory findings.
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 2 papers.
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
Jamestown Canyon virus (JCV) is a mosquito-borne orthobunyavirus that causes an acute febrile illness, meningitis or meningoencephalitis. Human infections in the USA are rare. A 59-year-old man was admitted with fever, headache and hallucinations and required transfer to intensive care due to worsening agitation. Lumbar puncture was significant for neutrophilic pleocytosis, low glucose and high protein. Cerebral spinal fluid (CSF) bacterial cultures were negative, however, the CSF analysis via ELISA returned positive for JCV IgM. Plaque reduction neutralisation tests on a serum sample revealed IgM for JCV with titres of 1:160, which confirmed the diagnosis of JCV meningoencephalitis as the titres for other arboviruses were low. The patient improved significantly with supportive care. Our case highlights an atypical laboratory presentation of neutrophilic pleocytosis on CSF in a viral meningoencephalitis and draws attention to the potential cross-reactivity with other arboviruses.
