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

Rapid, efficient generation of knock-in mice with targeted large insertions remains a major hurdle in mouse genetics. Here, we describe two-cell homologous recombination (2C-HR)-CRISPR, a highly efficient gene-editing method based on introducing CRISPR reagents into embryos at the two-cell stage, which takes advantage of the open chromatin structure and the likely increase in homologous-recombination efficiency during the long G2 phase. Combining 2C-HR-CRISPR with a modified biotin-streptavidin approach to localize repair templates to target sites, we achieved a more-than-tenfold increase (up to 95%) in knock-in efficiency over standard methods. We targeted 20 endogenous genes expressed in blastocysts with fluorescent reporters and generated reporter mouse lines. We also generated triple-color blastocysts with all three lineages differentially labeled, as well as embryos carrying the two-component auxin-inducible degradation system for probing protein function. We suggest that 2C-HR-CRISPR is superior to random transgenesis or standard genome-editing protocols, because it ensures highly efficient insertions at endogenous loci and defined 'safe harbor' sites.
