Sequence comparison of three infectious molecular clones of RD-114 virus.
Article in Virus genes, 2012. 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
RD-114 virus is a replication-competent feline endogenous retrovirus. RD-114 virus contaminates several feline and canine live attenuated vaccines and the issue of contamination of RD-114 virus in vaccines should be solved. To date, three infectious molecular clones (pSc3c, pCRT1, and pRD-UCL) have been reported. In this study, we sequenced the entire nucleotide sequence of pRD-UCL and compared the nucleotide sequences of the three infectious molecular clones. As a result, these three infectious clones were nearly identical with each other in gag-pol and env coding regions. These data support the notion that the active locus of infectious RD-114 virus is single in the feline genome. The length of long terminal repeat (LTR) of pCRT1 was 47 bp shorter than those of pSc3c and pRD-UCL. The 47-bp sequence named direct repeat A (DR-A) was duplicated in the U3 region in pSc3c and pRD-UCL. Although several potential enhancer binding sites are present in the DR-A, there was no significant difference in promoter activities between the LTRs of pRD-UCL and pCRT1 in two human cell lines. We also analyzed the splicing pattern of the RD-114 virus by reverse transcription-polymerase chain reaction and confirmed that RD-114 virus is a simple retrovirus. The data presented here will provide basic information about RD-114 virus to solve the contamination issue in live attenuated vaccines.
