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

Transgenic animals are invaluable tools in genetic studies, disease modeling, drug discovery, and biotechnology. However, the low efficiency of transgenic animal generation can be an obstacle to their application. Here, we report the generation of transgenic mice using PBatase, the piggyBat transposase from the little brown bat (Myotis lucifugus). PBatase exhibits detectable transposition activity in fertilized mouse eggs within a limited concentration range, although the overall activity was lower than that of PBase, the piggyBac transposase from the cabbage looper moth (Trichoplusia ni). Transgenic animals carrying low transgene copy numbers were successfully generated with high efficiency using PBatase, and the transgene was subsequently transmitted to the next generation. This technique will be useful for the generation of transgenic animals carrying single copies of a transgene.
