Influenza B viruses are more susceptible to high temperatures than influenza A viruses.
Article in Npj viruses, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Seasonal influenza is caused by two subtypes of influenza A virus (A/H1N1 and A/H3N2) and two lineages of influenza B viruses (B/Victoria-lineage and B/Yamagata-lineage). Seasonal influenza viruses replicate efficiently in the human upper respiratory tract, where the temperature is 33 °C. In this study, we investigated the susceptibility of seasonal influenza A and B viruses to different temperatures. We examined the differences in viral replication efficiency inside cultured cells and in infectious titre outside cultured cells at different temperatures (i.e., 33 °C, 37 °C, and 39 °C). We found that there were differences in temperature sensitivity between influenza A and B viruses, with influenza B viruses being more temperature sensitive. In addition, we found that cells cultured at 39 °C and infected with influenza B virus showed decreased expression of HA protein with receptor-binding activity on the cell surface. Our findings contribute to our understanding of the properties of seasonal influenza viruses.
