1 · What the graph read from it

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.

2 · The registry

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

Foamy virus (FV) vectors are promising for hematopoietic stem cell (HSC) gene therapy but preclinical data on the clonal composition of FV vector-transduced human repopulating cells is needed. Human CD34(+) human cord blood cells were transduced with an FV vector encoding a methylguanine methyltransferase (MGMT)P140K transgene, transplanted into immunodeficient NOD/SCID IL2Rγ(null) mice, and selected in vivo for gene-modified cells. The retroviral insertion site profile of repopulating clones was examined using modified genomic sequencing PCR. We observed polyclonal repopulation with no evidence of clonal dominance even with the use of a strong internal spleen focus forming virus promoter known to be genotoxic. Our data supports the use of FV vectors with MGMTP140K for HSC gene therapy but also suggests additional safety features should be developed and evaluated.
