1 · What the graph read from it

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.

2 · The registry

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

We herein report a 49-year-old man with a fever, diagnosed with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. After two weeks of hospitalization, he suddenly mentioned visual field impairment. Computed tomography and magnetic resonance imaging revealed white matter damage and vasogenic edema. Cerebrospinal fluid showed increased levels of interleukin (IL)-6. His symptoms and white matter lesion deteriorated. After treatment with intravenous methylprednisolone therapy and plasmapheresis, his symptoms and white matter lesion improved gradually. We suspect that our patient was affected by a secondary hyperinflammatory syndrome related to cytokines, alone or in combination with direct viral injury through endothelial cell damage. The IL-6 levels were elevated only in the cerebrospinal fluid, suggesting focal central nervous system inflammation.
