Repeated avian infectious bronchitis virus infections within a single chicken farm.
Article in The Journal of veterinary medical science, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Genotyping of avian infectious bronchitis virus (IBV) was performed on trachea and kidney samples of six chickens obtained from a single farm in Japan. Using two primer sets targeting the spike (S) protein gene, the S1 and S2 regions of DNA fragments were amplified. Sequences of amplified S1 fragments extracted from both organs were identical among the six chickens, showing a JP-I genotype. Sequences of amplified S2 fragments differed between trachea and kidney samples. The kidney profile showed a group IV genotype, whereas the trachea profile showed an unclassified group. This result showed that two different IBVs infected the six chickens. The first IBV infection induced poor protective immunity in this farm, permitting a second IBV infection to occur.
