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

A difficult genome editing goal is the site-specific insertion of large genetic constructs. Here we describe the GENEWRITE system, where site-specific targetable activity of Cas endonucleases is coupled with the reverse transcriptase activity of the ORF2p protein of the human retrotransposon LINE-1. This is accomplished by providing two RNAs: a guide RNA targeting Cas endonuclease activity and an appropriately designed payload RNA encoding the desired insertion. Using E. coli as a simple platform for development and deployment, we show that with proper payload design and co-expression of helper proteins, GENEWRITE can enable insertion of large genetic payloads to precise locations, although with off-target effects, using the described approach. Based upon these results, we describe a potential strategy for implementation of GENEWRITE in more complex systems.
