Genomic rearrangements of retroviral vectors carrying two genes in F9 EC cells.
Article in Virus genes, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
We have used two classes of double-expression retroviral vectors for the expression of foreign genetic information in embryonal carcinoma cell lines. The splice-vector pM5neo takes advantage of mutated sequences that mediate an LTR-driven expression in F9 EC cells. The second vector (pXT1 type) uses an internal HSV-tk promoter as the control element for the transcription of the second gene. Genomic analysis of DNA from infected F9 cell lines revealed that most of the proviruses have rearranged upon integration into the host genome. This reorganization always included the nonselected gene and is sequence independent, but depends on the selective pressure applied. No retroviral genomic rearrangements were observed in F9 cells infected with pM5 proviruses carrying only the neo resistance gene. On the contrary, gross rearrangements were found in cells infected with parental pXT1 retroviruses. In both vectors the transcriptional activity was very low. A direct correlation between selective pressure, proviral reorganization, and transcription was observed.
