Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease With False-Positive Results in SARS-CoV-2 Antigen Tests: A Case Report.
Article in Cureus, 2022. 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 23-year-old man presented with headache, fever, and urinary retention. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antigen tests were positive, but SARS-CoV-2 polymerase chain reaction (PCR) results were negative. MRI showed long spinal cord lesions. Due to positive serum and cerebrospinal fluid myelin oligodendrocyte glycoprotein (MOG) antibodies, we made the diagnosis of MOG-associated disease. We concluded that the antigen tests were false positives because SARS-CoV-2 IgM and IgG were not elevated. Although the mechanism behind the false-positive results is unclear, physicians should consider the possibility of a false-positive result in the SARS-CoV-2 antigen test.
