Recovery of culturable Streptococcus pyogenes from swabs stored at different temperatures.
Article in Environmental microbiology reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Improving our understanding of superficial Streptococcus pyogenes (Strep A) carriage and transmission necessitates robust sampling methods. Here, we compared the effect of storing swab samples in fridge (+4°C) and freezer (-20°C) conditions on the recovery of laboratory-cultured S. pyogenes. Streptococcus pyogenes colony-forming units progressively declined at +4°C, but not at -20°C, over 2 weeks. Results demonstrate that freezing is preferable over refrigeration for storage and transport of skin and throat swabs to ensure that culturing accurately reflects the true results of sampling. This is particularly important in remote community research and practice when immediate incubation is not possible or batch processing is most practical, increasing the elapsed time between collection and laboratory analysis. The study suggests that temperature negatively affects S. pyogenes viability and provides a method to further investigate the role of other environmental factors affecting S. pyogenes transmission.
