Identification and characterization of pigeon adenovirus 1 as an emerging pathogen in pigeons from Northern and Northwest China.
Article in BMC veterinary research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundIn 2022, a new infectious disease characterized by severe acute hepatitis, sudden death, and high mortality among breeding pigeons, was reported in China.
resultsIn naturally infected pigeons, key necropsy findings comprised hepatic swelling with patchy hemorrhage and pericardial effusion. Histopathological examination further revealed degeneration, necrosis, and basophilic intranuclear inclusion bodies affecting hepatocytes, cardiomyocytes, and vascular endothelial cells. Transmission electron microscopy revealed a typical icosahedral virus structure and crystal-like arrangement of viral particles in the nucleus. Metagenomic next-generation sequencing (mNGS) of pericardial effusion samples revealed the presence of pigeon adenovirus. Sequencing analysis of the hexon and fiber-2 genes suggested that it constituted pigeon adenovirus 1 (PiAdV-1). The complete genome of CH/BJ/1/2022 was determined to be 48,071 nucleotides in length, with a 10-amino acid deletion in the fiber-2 gene at residues 627-636 and a 95-animo acid insertion in the 100 K gene at residue 75. The same disease was reproduced in pigeons by experimental infection.
conclusionCollectively, our analyses confirmed that the etiological agent was PiAdV-1, an emerging pathogen that causes severe acute hepatitis and high mortality in pigeons. This virus merits close attention because it could be catastrophic for the pigeon industry.
