Emerging threats of H5N1 clade 2.3.4.4b: cross-species transmission, pathogenesis, and pandemic risk.
Review in Frontiers in cellular and infection microbiology, 2025. 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
H5N1 is a highly pathogenic avian influenza virus (HPAIV) with zoonotic potential, posing a significant risk to animal health, agriculture, and human public health. A particular strain, clade 2.3.4.4b, has spread globally and has been detected in various mammalian species-including cattle and a limited number of human cases-highlighting its potential to spark a pandemic. Investigating this specific clade represents a crucial step toward the development of effective preventive and therapeutic strategies. This mini-review aims to outline the etiology and pathophysiological mechanisms driving the current bird flu outbreak in cattle. A targeted literature search was conducted in PubMed for studies published between 2003 and 2025 using keywords such as "bird flu", "cattle", "mammals", "H5N1", and "pathogenesis". This review explores the pathogenic mechanisms and clinical manifestations associated with HPAIV H5N1 infections in mammals specially in cattle. A key hypothesis is that the ongoing outbreak is fueled by molecular adaptations in the virus that enhance its ability to cross species barriers. As these mechanisms continue to be uncovered, there is a pressing need for high-quality research to inform pandemic preparedness, guide effective control strategies, and support the development of targeted vaccines and antiviral therapies.
