Characterisation of different forms of the accessory gp3 canine coronavirus type I protein identified in cats.
Article in Virus research, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
ORF3 is a supplemental open reading frame coding for an accessory glycoprotein gp3 of unknown function, only present in genotype I canine strain (CCoV-I) and some atypical feline FCoV strains. In these latter hosts, the ORF3 gene systematically displays one or two identical deletions leading to the synthesis of truncated proteins gp3-Δ1 and gp3-Δ2. As deletions in CoV accessory proteins have already been involved in tissue or host switch, studies of these different gp3 proteins were conducted in canine and feline cell. All proteins oligomerise through covalent bonds, are N-glycosylated and are maintained in the ER in non-infected but also in CCoV-II infected cells, without any specific retention signal. However, deletions influence their level of expression. In canine cells, all proteins are expressed with similar level whereas in feline cells, the expression of gp3-Δ1 is higher than the two other forms of gp3. None of the gp3 proteins modulate the viral replication cycle of heterologous genotype II CCoV in canine cell line, leading to the conclusion that the gp3 proteins are probably advantageous only for CCoV-I and atypical FCoV strains.
