Tracking of specific integrant clones in dogs treated with foamy virus vectors.
Article in Human gene therapy, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Vector integration can lead to proto-oncogene activation and malignancies during hematopoietic stem cell gene therapy. We previously used foamy virus vectors to deliver the CD18 gene under the control of an internal murine stem cell virus promoter and successfully treated dogs with canine leukocyte adhesion deficiency. Here we have tracked the copy numbers of 11 specific proviruses found in these animals for 36-42 months after transplantation, including examples within or near proto-oncogenes, tumor suppressor genes, and genes unrelated to cancer. We found no evidence for clonal expansion of any of the clones, including those with proviruses in the MECOM gene (MDS1-EVI1 complex). These results suggest that although foamy virus vectors may integrate near proto-oncogenes, this does not necessarily lead to clonal expansion and malignancies. Additionally, we show that copy number estimates of these specific proviruses based on linker-mediated PCR results are different from those obtained by quantitative PCR, but can provide a qualitative assessment of provirus levels.
