Association of Bariatric Surgery with Clinical Outcomes of SARS-CoV-2 Infection: a Systematic Review and Meta-analysis in the Initial Phase of COVID-19 Pandemic.

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
introductionObesity worsens clinical outcomes of coronavirus disease 2019 (COVID-19). The aim of this study was to measure the association between history of bariatric surgery and the severity of COVID-19.
methodsData source included PubMed/MEDLINE, Scopus, Google Scholar, and pre-print servers between January and November 1, 2020. Literature was screened and selected to extract the relevant data. The two outcomes of this meta-analysis were the difference in mortality and hospitalization rates in patients with SARS-CoV-2 infection with and without history of bariatric surgery. Random-effect models were used to estimate the pooled effects.
resultsThe systematic review yielded 3 retrospective studies on 9022 patients. The risk of mortality without previous bariatric surgery was 133 per 1000 cases and its risk with previous bariatric surgery was 33 per 1000 (summary OR 0.22, 95% CI 0.19-0.26). No heterogeneity was observed between the included studies (I
conclusionFindings of this meta-analysis of observational studies suggest that prior bariatric surgery is associated with a lower rate of mortality and hospital admission in patients with obesity who become infected with SARS-CoV-2. Confirmation of these findings will require larger studies with better quality data.
