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

Lentiviral vectors are very efficient at transducing dividing and quiescent cells, which makes them highly useful tools for genetic analysis and gene therapy. Traditionally this efficiency was considered dependent on provirus integration in the host cell genome; however, recent results have challenged this view. So called integration-deficient lentiviral vectors (IDLVs) can be produced through the use of integrase mutations that specifically prevent proviral integration, resulting in the generation of increased levels of circular vector episomes in transduced cells. These lentiviral episomes lack replication signals and are gradually lost by dilution in dividing cells, but are stable in quiescent cells. Compared to integrating lentivectors, IDLVs have a greatly reduced risk of causing insertional mutagenesis and a lower risk of generating replication-competent recombinants (RCRs). IDLVs can mediate transient gene expression in proliferating cells, stable expression in nondividing cells in vitro and in vivo, specific immune responses, RNA interference, homologous recombination (gene repair, knock-in, and knock-out), site-specific recombination, and transposition. IDLVs can be converted into replicating episomes, suggesting that if a clinically applicable system can be developed they would also become highly appropriate for stable transduction of proliferating tissues in therapeutic applications.
