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 have investigated the practicality of implementing a strategy for site-specific editing by homologous recombination in zebrafish analogous to that developed by Rong and Golic (Rong and Golic in Genetics 157:1307-1312, 2001) in Drosophila melanogaster. We analysed approximately 7,300 offspring from 22 crosses and demonstrated successful excision of the gene editing construct but failed to detect either gene editing or the random integration of the intact editing construct subsequent to excision. The clustering of events in our data set demonstrates that the excision events are not occurring independently and emphasise that a promoter driving high level, tissue-specific transcription in meiotic cells is likely to be necessary if this general approach to site-specific editing by homologous recombination is to fulfil its potential.
