Detection of Felis catus papillomavirus-derived genes in squamous cell carcinoma tissues in cats in Japan.

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
Felis catus papillomavirus (FcaPV) was first discovered in 2002. Seven genotypes (FcaPV-1/-2/-3/-4/-5/-6/-7) have been reported to date, at least one of which (FcaPV-2) is suggested to be implicated in squamous cell carcinoma (SCC); however, relevant epidemiological data on Japanese cats are limited. There is one report on relatively low FcaPV-2 prevalence in cats with SCC, largely in the Tokyo region. In this study, we investigated the prevalence of each FcaPV genotype in cats with SCC largely drawn from a peripheral region of Japan (Kyushu). Formalin-fixed paraffin-embedded (FFPE) specimens from 107 cats with SCC were subjected to DNA extraction for type-specific PCR assays, followed by confirmatory nucleotide sequencing. Overall, 16 cases (15.0%) were positive for FcaPV, and the results detected for FcaPV-1/-2/-3/-4/-5/-6/-7 were 0/107 (0.0%), 7/107 (6.5%), 4/107 (3.7%), 1/107 (0.9%), 3/107 (2.8%), 1/107 (0.9%), and 1/107 (0.9%), respectively. Our results suggest that FcaPV-2 is the prevalent papillomavirus type in cats with SCC across Japan, but the figure is lower than in other countries. This is also the first report on the detection of FcaPV-6 and FcaPV-7 in Japan, which previously have only been reported in Australia and New Zealand, respectively.
