A case-control study of factors associated with SARS-CoV-2 infection among healthcare workers in Colombia.

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
backgroundHealthcare Workers (HCW) are repeatedly exposed to SARS-CoV-2 infection. The aim of this study was to identify factors associated with SARS-CoV-2 infection among HCW in one of the largest cities in Colombia.
methodsWe conducted a case-control study, where cases had a positive reverse transcription-polymerase chain reaction and controls had a negative result. Participants were randomly selected and interviewed by phone. Analyses were performed using logistic regression models.
resultsA total of 110 cases and 113 controls were included. Men (AdjOR 4.13 95% CI 1.70-10.05), Nurses (AdjOR 11.24 95% CI 1.05-119.63), not using a high-performance filtering mask (AdjOR 2.27 95% CI 1.02-5.05) and inadequate use of personal protective equipment (AdjOR 4.82 95% CI 1.18-19.65) were identified as risk factors. Conversely, graduate (AdjOR 0.06 95% CI 0.01-0.53) and postgraduate (AdjOR 0.05 95% CI 0.005-0.7) education, feeling scared or nervous (AdjOR 0.45 95% CI 0.22-0.91), not always wearing any gloves, caps and goggles/face shields (AdjOR 0.10 95% CI 0.02-0.41), and the use of high-performance filtering or a combination of fabric plus surgical mask (AdjOR 0.27 95% CI 0.09-0.80) outside the workplace were protective factors.
conclusionThis study highlights the protection provided by high-performance filtering masks or double masking among HCW. Modifiable and non-modifiable factors and the difficulty of wearing other protective equipment needs to be considered in designing, implementing and monitoring COVID-19 biosafety protocols for HCW.
