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

Target-specific genome editing using engineered nucleases has become widespread in various fields. Long gene knock-in and single-base substitutions can be performed by homologous recombination (HR), but the efficiency is usually very low. To improve the efficiency of knock-in with single-stranded oligo DNA nucleotides (ssODNs), we have investigated optimal design of ssODNs in terms of the blocking mutation, orientation, size, and length of homology arms to explore the optimal parameters of ssODN design using reporter systems for the detection of single-base substitutions. We have also investigated the difference in knock-in efficiency among the delivery forms and methods of Cas9 and sgRNA. The knock-in efficiencies for optimized ssODNs were much higher than those for ssODNs with no blocking mutation. We have also demonstrated that Cas9 protein/sgRNA ribonucleoprotein complexes (Cas9-RNPs) can dramatically reduce the re-cutting of the edited sites.
