SARS-CoV-2 RNA stability in dry swabs for longer storage and transport at different temperatures.
Article in Transboundary and emerging diseases, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
During the current COVID-19 pandemic, different methods have been used to evaluate patients with suspected SARS-CoV-2 infection. In this study, we experimentally evaluate the ability of spiked saliva-moist swabs and spiked swabs without any transport medium to retain SARS-CoV-2 for storage and transport at different environmental settings during different incubation time periods. Our results show that at ambient temperature of 20°C, SARS-CoV-2 RNA remains stable for up to 9 days allowing a long-time span for transport and storage without compromising clinical results. Additionally, this study demonstrates that saliva-moist swabs can also be stored at -20°C and +4°C for up to 26 days without affecting RT-qPCR results. Our data are relevant for low-and middle-income countries, which have limited access to rapid refrigerated transport and storage of samples representing an economical alternative. Finally, our study demonstrates the practical and economic advantage of using swabs without transport medium.
