Evolution and Spread of Y280-Lineage H9N2 Low Pathogenicity Avian Influenza Viruses in Korea, 2020-2023.

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
In 2020, Y280-lineage H9N2 low pathogenic avian influenza was detected in South Korea for the first time. Active surveillance from live bird markets (LBMs) and farms revealed the continuous circulation of Y280-lineage H9N2 viruses, replacing the previously indigenous Y439-lineage and becoming dominant in South Korea. Antigenic mapping showed a substantial antigenic difference between the Y280 and Y439-lineage viruses. Bayesian phylodynamic approach suggests the introduction of Y280-lineage viruses from China and revealed the frequent exchange of viruses between LBM and farms. The presence of mammalian adaptation markers and high binding affinity to human-type sialic acid receptor raise a concern on interspecies transmission of the viruses to mammals. These findings underscore the importance of continued genomic surveillance to monitor the evolution of H9N2 viruses and assessment of zoonotic potential.
