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

We describe an experimental approach for generating mutant alleles in rat spermatogonial stem cells (SSCs) using Sleeping Beauty (SB) transposon-mediated insertional mutagenesis. The protocol is based on mobilization of mutagenic gene-trap transposons from transfected plasmid vectors into the genomes of cultured stem cells. Cells with transposon insertions in expressed genes are selected on the basis of activation of an antibiotic-resistance gene encoded by the transposon. These gene-trap clones are transplanted into the testes of recipient males (either as monoclonal or polyclonal libraries); crossing of these founders with wild-type females allows the insertions to be passed to F(1) progeny. This simple, economic and user-friendly methodological pipeline enables screens for functional gene annotation in the rat, with applicability in other vertebrate models where germ line-competent stem cells have been established. The complete protocol from transfection of SSCs to the genotyping of heterozygous F(1) offspring that harbor genomic SB gene-trap insertions takes 5-6 months.
