Characterization of an Emerging Recombinant Duck Circovirus in Northern Vietnam, 2023-2024.
Article in Viruses, 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
This study aimed to characterize the duck circovirus circulating in Northern Vietnam based on complete genome sequences. Between 2023 and 2025, 45 pooled tissue samples were collected from nine duck flocks in several provinces in Northern Vietnam. Of the 45 samples tested, 16 (35.56%) were positive for the DuCV genome, as determined using conventional polymerase chain reaction. Nine representative strains were selected for viral genome sequencing. The results indicated that the complete Vietnamese DuCV genomes were from 1992 to 1995 bp in length, and the degree of nucleotide identity shared among them ranged from 96.88% to 99.84%. Phylogenetic analysis of the complete genomes showed that the nine Vietnamese DuCV strains belonged to genotype I, subgenotypes Ia (two strains), Ib (four strains), and Ic (three strains). These viral strains were genetically related to viruses reported in China from 2019 to 2023. Recombination events occurred on the Cap gene sequences of three Vietnamese DuCV strains (Vietnam/VNUA-102/2023, Vietnam/VNUA-225/2023, and Vietnam/VNUA-318/2024). One positive selection was detected on the Rep protein sequence.
