Incidence of Guillain-Barré Syndrome (GBS) after COVID-19 Vaccination: a Systematic Review and Meta-Analysis.
Review in Maedica, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
backgroundGlobal vaccination against COVID-19 will help nations to overcome the pandemic stage as soon as possible. Guillain-Barré syndrome (GBS) is an acute immune-mediated inflammatory disease of the peripheral nerves (PNS) that is reported as a complication of both COVID-19 and vaccines. Up to now, case reports regarding the incidence of GBS have been reported after different COVID-19 vaccines worldwide. So, the aim of this systematic review and meta-analysis is to estimate the pooled incidence of GBS after COVID-19 vaccination.
methodsTwo expert researchers conducted a systematic search in PubMed, Scopus, EMBASE, Web of Science, Google Scholar as well as gray literature in order to find relevant articles published before September 2022.
resultsAfter deleting duplicates, we found 1021 articles, of which 458 studies were further evaluated. A final number of 21 studies remained for meta-analysis, with most of those being from the USA, UK and Mexico. Follow-up duration was between 21-42 days. Out of the total number of 2.35x109 patients included in the final meta-analysis, 3654 subjects developed GBS after vaccination, most of whom were males. Incidence of GBS per million ranged between 0.23 and 9.8. The pooled incidence of GBS following vaccination was 0%.
