Loss of Infectivity of Influenza Virus and SARS-CoV‑2 during Aerosol Sampling.
Article in Environmental science & technology letters, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Our understanding of transmission of influenza virus and other respiratory viruses is limited by the difficulty of detecting infectious viruses in aerosol particles. Most aerosol sampling methods are believed to contribute to virus inactivation, but the magnitude of this sampling artifact is unknown. To investigate this question, we aerosolized influenza A virus (IAV) and SARS-CoV-2 suspended in human saliva into a small chamber (3.7 L). Aerosols settled for 10 min onto either cells or a thin layer of liquid medium that was immediately transferred to cells for plaque assay. Aerosols that deposited directly onto cells led to the formation of 100× more plaque forming units (PFU) compared to aerosols that deposited first into liquid medium. Further experiments ruled out uneven aerosol distribution in the chamber or inefficient virus recovery as causes of this discrepancy. These findings indicate that aerosolized IAV and SARS-CoV-2 lost infectivity by approximately 2 log
