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

Cas9, a CRISPR-associated RNA-guided nuclease, has been rapidly adopted as a tool for biochemical and genetic manipulation of DNA. Although complexes between Cas9 and guide RNAs (gRNAs) offer remarkable specificity and versatility for genome manipulation, mis-targeted events occur. To extend the understanding of gRNA::target homology requirements, we compared mutational tolerance for a set of Cas9::gRNA complexes in vitro and in vivo (in Saccharomyces cerevisiae). A variety of gRNAs were tested with variant libraries based on four different targets (with varying GC content and sequence features). In each case, we challenged a mixture of matched and mismatched targets, evaluating cleavage activity on a wide variety of potential target sequences in parallel through high-throughput sequencing of the products retained after cleavage. These experiments evidenced notable and consistent differences between in vitro and S. cerevisiae (in vivo) Cas9 cleavage specificity profiles including (i) a greater tolerance for mismatches in vitro and (ii) a greater specificity increase in vivo with truncation of the gRNA homology regions.
