The Role of Preprocedure Screening of SARS-CoV-2 Infection: A Tertiary Care Medical Center Analysis.

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
purposeThis study aimed to understand the prevalence of asymptomatic COVID-19 infection among patients undergoing endoscopic procedures at a tertiary care hospital. The results allow prediction of the magnitude of cases which this endoscopic service might witness in the next months and planning of future actions accordingly.
methodsThis retrospective study was conducted in the gastroenterology department of a large urban tertiary care medical center from October 15, 2020, to November 15, 2020. In this institution, all patients proposed for endoscopic procedures under deep sedation must be submitted to reverse transcription polymerase chain reaction (RT-PCR) for SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) detection. These results were thoroughly reviewed.
resultsIn the 1-month period, a total of 833 different procedures were done in 833 patients admitted to the endoscopy unit. Of these, 167 (20%) were submitted to nasal swab for SARS-CoV-2. Only 1 (0.6%) was positive for this infection, and her procedure was postponed. This RT-PCR-positive patient was not symptomatic for CO-VID-19 infection at the time of preprocedure screening. She had no positive contacts for COVID-19 and had not traveled outside the country.
conclusionWe found that the proportion of patients proposed for an endoscopic intervention who were asymptomatic carriers of SARS-CoV-2 was low. However, only one fifth of patients were tested and, considering the proportion of 0.6%, it is reasonable to consider that exposure of healthcare workers and other patients can occur. So, all prevention measures must be strictly followed. However, the cost-benefit of an universal testing policy must be proven.
