Factors associated with onward SARS-CoV-2 transmission among household and dormitory contacts of cases in Brunei Darussalam, August 2021 to February 2022: A retrospective cohort study.

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
Objectives: We aimed to determine the factors associated with contacts testing positive within a typical household and worker dormitory clusters during the COVID-19 Delta and Omicron waves. Methods: We performed retrospective analyses of national COVID-19 cases and contacts data sets in Brunei Darussalam, from August 2021 to mid-February 2022. Results: We identified 22,540 laboratory-confirmed cases, whereby 50.9% and 25.9% were from household and dormitory clusters, respectively. The median (interquartile range) serial interval for households (3 days [2-5]) was shorter than that of dormitories (5 days [3-9], Conclusion: Our findings suggest a significant role of housing composition in within-household transmission dynamics.
