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

Integrative gene transfer methods are limited by variable transgene expression and by the consequences of random insertional mutagenesis that confound interpretation in gene-function studies and may cause adverse events in gene therapy. Site-specific integration may overcome these hurdles. Toward this goal, we studied the transcriptional and epigenetic impact of different transgene expression cassettes, targeted by engineered zinc-finger nucleases to the CCR5 and AAVS1 genomic loci of human cells. Analyses performed before and after integration defined features of the locus and cassette design that together allow robust transgene expression without detectable transcriptional perturbation of the targeted locus and its flanking genes in many cell types, including primary human lymphocytes. We thus provide a framework for sustainable gene transfer in AAVS1 that can be used for dependable genetic manipulation, neutral marking of the cell and improved safety of therapeutic applications, and demonstrate its feasibility by rapidly generating human lymphocytes and stem cells carrying targeted and benign transgene insertions.
