Epidemiological Characteristics and Genetic Diversity of Chicken Infectious Anemia Virus (CIAV) in Guangdong Province, China.
Article in Veterinary sciences, 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
Chicken infectious anemia virus (CIAV) causes immunosuppression in poultry, leading to substantial global economic losses through both vertical and horizontal transmission. Since 2014, frequent outbreaks have been reported in southern China; however, the epidemiology of CIAV in Guangdong Province remains poorly defined. Between July 2018 and March 2022, we collected 105 tissue samples and 786 serum samples from poultry in nine cities. PCR/qPCR assays targeting the VP1 gene confirmed CIAV infection, and positive tissues inoculated into MSB1 cells yielded four isolates (GDHZ1, GDHZ2, GDJM, GDLF). Phylogenetic analysis demonstrated that GDHZ1, GDJM, and GDLF clustered within clade A1, whereas GDHZ2 belonged to clade A2. All isolates shared glutamine (Q) at position 394, together with virulence-associated amino acid signatures (75V, 89T, 125L, 139K, 141Q, 144E). Serological testing indicated a high prevalence, with 627 of 786 samples positive (79.77%). The relatively low proportion of virus-positive tissues and successful isolations may reflect viral tropism or limitations in detection sensitivity. These findings enhance understanding of CIAV molecular epidemiology in Guangdong and provide evidence to inform surveillance, vaccination strategies, and control measures.
