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

Efficient exogenous DNA integration can be mediated by Cas9 through the non-homology end-joining pathway. However, such integrations are often imprecise and contain a variety of mutations at the junctions between the external DNA and the genomic loci. Here we describe a microhomology-dependent targeted integration method, designated MITI, for precise site-specific gene insertions. We found that the MITI strategy yielded higher knock-in accuracy than Cas9 HITI for the insertion of external DNA and tagging endogenous genes. Furthermore, in combination with negative selection and four different CrRNAs targeting donor vectors and genome-targeted sites with a CrRNA array, MITI facilitated precise ligation at all junctions. Therefore, our Cas12a-based MITI method increases the repertoire of precision genome engineering approaches and provides a useful tool for various gene editing applications.
