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

Coronavirus disease 2019 (COVID-19) has been shown to be associated with a lot of neurological complications, of whom Guillain-Barre syndrome (GBS) is an important post-infectious consequentiality. More than 220 patients with GBS have been reported thus far. We intend to share our experience with five patients of GBS where one of them had severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the cerebrospinal fluid (CSF). This is the first-ever report demonstrating the presence of SARS-CoV-2 in the CSF of an adult patient; a similar occurrence has recently been described in a pediatric patient. We wish to emphasize the fact that commonly GBS occurs as a result of a post-infectious process but in a few cases where the symptoms of COVID-19 and GBS occur concurrently, corresponding to the viremic phase, separate pathogenesis needs to be thought of. This para-infectious nature is exemplified by the presence of virus in the cerebrospinal fluid of one of our patients. We review the neuroinvasive potential of SARS-Cov-2 in this regard and draw parallels with Cytomegalovirus, Zika virus, and Human Immunodeficiency virus-associated occurrences of GBS.
