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

In a gene targeting experiment, the generation of a targeting construct often requires complex DNA manipulations. We developed a set of cassettes and plasmids useful for creating targeting vectors to modify the mammalian genome. A positive selection marker cassette (PGK/EM7p-npt), which included dual prokaryotic and eukaryotic promoters to permit consecutive selection for recombination in Escherichia coli and then in mouse embryonic stem cells, was flanked by two FRT-loxP sequences. The PGK/EM7p-npt cassette was placed between the minimum regions of a Tn7 transposable element for insertion into another DNA by means of Tn7 transposase in vitro. We also constructed a plasmid having a loxP-Zeo-loxP cassette between the modified Tn5 outer elements. These cassettes can be integrated randomly into a given genomic DNA through the in vitro transposition reaction, thus producing a collection of genomic segments flanked by loxP sites (floxed) at various positions without the use of restriction enzymes and DNA ligase. We confirmed that this system remarkably reduced the time and labor for the construction of complex gene targeting vectors.
