Novel mutation of avian leukosis virus subgroup J from Tibetan chickens.
Article in Poultry science, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Tibetan chickens are descendants of the ancestral red jungle fowl Gallus gallus. Very little is known about pathogens in Tibetan chickens living in the high-altitude environment. Here, we report for the first time the detection and isolation of avian leukosis virus from Tibetan chickens, with all the avian leukosis virus-positive samples belonging to subgroup J. Phylogenetic analysis of the sequence revealed these viruses were in a new branch compared with previous reports. The 3'-end of the pol gene in the new strains showed 8-amino acid deletion, with 2 strains displaying a large-scale deletion in the hr2 region of gp85 protein. Among all the strains, several mutations in the primer binding site leader sequence and untranslated region, which came from Rous-associated virus, were identified. It is interesting that some of these mutations may have contributed to the competitive advantages to these isolates as observed from their increased replication in vitro. These results indicated that the virus isolates from Tibetan chickens can have competitive advantage over the other strains circulating in the poultry population in future.
