Homologous SV40 RNA trans-splicing: a new mechanism for diversification of viral sequences and phenotypes.
Article in RNA biology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Simian Virus 40 (SV40) is a polyomavirus found in both monkeys and humans, which causes cancer in some animal models. In humans, SV40 has been reported to be associated with cancers but causality has not been proven yet. The transforming activity of SV40 is mainly due to its 94-kD large T antigen, which binds to the retinoblastoma (pRb) and p53 tumor suppressor proteins, and thereby perturbs their functions. Here we describe a 100 kD super T antigen harboring a duplication of the pRB binding domain that was associated with unusual high cell transformation activity and that was generated by a novel mechanism involving homologous RNA trans-splicing of SV40 early transcripts in transformed rodent cells. Enhanced trans-splice activity was observed in clones carrying a single point mutation in the large T antigen 5' donor splice site (ss). This mutation impaired cis-splicing in favor of an alternative trans-splice reaction via a cryptic 5'ss within a second cis-spliced SV40 pre-mRNA molecule and enabled detectable gene expression. Next to the cryptic 5'ss we identified additional trans-splice helper functions, including putative dimerization domains and a splice enhancer sequence. Our findings suggest RNA trans-splicing as a SV40-intrinsic mechanism that supports the diversification of viral RNA and phenotypes.
