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 based constructs represent a recent development in the generation of transgenic animals. The ease of use, and the fact that the same backbone vectors can be used to down-modulate endogenous gene expression and to produce transgenic animals overexpressing a gene of interest, have fuelled growing interest in this technology. In this study, we have used a lentiviral delivery system to generate transgenic mice expressing altered levels (up or downregulated) of a gene of interest. Although this lentiviral-based approach led to high levels of transgenesis and germ line transmission, a wide variation in transgene expression was observed in most first and second generation mouse lines. In particular, despite the segregation of integrants into single-copy expressing mouse lines, transgene expression appeared to be the target of epigenetic regulatory mechanism, often causing the coexistence of high and low transgene expressing cells within a given tissue such as blood peripheral lymphocytes. The establishment and analysis of large number of mouse lines may therefore be required to select a stable transgenic line with pancellular expression of a gene of interest using this lentiviral-based approach.
