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

backgroundConcerns regarding the aerosolized transmission of SARS-CoV-2 via SS have caused significant apprehension among surgeons related to the use of minimally invasive surgery (MIS) during the COVID19 pandemic. While a limited number of studies have previously demonstrated the presence of viral material in SS, no comprehensive systematic review exists on the subject of viral transmission in SS. Methods A systematic review of the literature was conducted as per PRISMA guidelines. MEDLINE, EMBASE, and CENTRAL databases were searched for publications reporting the primary outcome of the presence of viral particles in SS and secondary outcomes of indices suggesting transmission of viable virus particles in SS producing clinically important infection. All human, animal, and in vitro studies which used accepted analytic techniques for viral detection were included. A meta-analysis was not complete due to methodologic heterogeneity and inconsistent reporting of outcomes of interest.

results23 publications addressed the presence of viral components in SS, and 19 (83%) found the presence of viral particles in SS. 21 publications additionally studied the ability of SS to induce clinically relevant infection in host cells, with 9 (43%) demonstrating potential for viral transmission.

conclusionEvidence exists for viral transmission via SS. However, HPV remains the only virus with documented transmission to humans via SS. While meaningful translation into practical guidelines during the COVID pandemic remains challenging, no evidence exists to suggest increased risk in MIS.
