Comparative sequence analysis of full-length genome of FIPV at different tissue passage levels.
Article in Virus genes, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Feline infectious peritonitis virus (FIPV), an alpha Coronavirus, is the causative agent of a fatal immune mediated disease in cats. It is currently unclear if this virus circulates in the field or develops in felines that are infected with Feline enteric coronavirus. To better understand the genomic changes associated with viral adaptation, we sequenced the complete genomes of FIPV WSU 79-1146 at different tissue passage levels: passage 1, passage 8, and passage 50 tissue culture. Twenty-one amino acid differences were observed in the polyprotein 1a/ab between the different passages. Only one residue change was observed in the spike glycoprotein, which reverted back on subsequent passages, four changes were observed in the 3c protein, and one change was observed in each 3a, small membrane, nucleocapsid and 7a proteins. The mutation rate was calculated to be 5.08-6.3 × 10(-6) nucleotides/site/passage in tissue culture suggesting a relatively stable virus. Our data show that FIPV has a low mutation rate as it is passed in cell culture but has the capacity for change specifically in nsp 2, 3c, and 7b as it is passed in cell culture.
