Highly Pathogenic Avian Influenza A (H5N1) Infection in Bearded Vultures in Spain.
Article in Zoonoses and public health, 2025. 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
We report mortality in bearded vultures ( Gypaetus barbatus ) associated with highly pathogenic avian influenza HPAI A H5N1 clade 2.3.4.4b, responsible for the current HPAI panzootic. Between April and May 2022, a total of five bearded vultures from Spain, four free-ranging and one captive individual, were found dead in their nest or with acute symptoms of disease. Complete necropsies were performed and histopathological, immunohistochemistry and molecular analyses were carried out. The presence of the HPAI H5N1 virus was confirmed in different organs, oropharyngeal and cloacal swabs and feathers from the affected individuals. The complete viral genome was obtained from three of the affected bearded vultures. Phylogenetic analyses revealed that the sequences obtained from the free-ranging individuals and the captive specimen belonged to the clade 2.3.4.4b and clustered separately. Furthermore, it supports that direct or indirect contact with other sympatric wild birds could be the most likely source of infection. This research highlights the susceptibility of the endangered bearded vulture to HPAI H5N1, thereby contributing to the broader understanding of the virus's host range.
