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

The CRISPR-Cas system holds great promise in the treatment of diseases caused by genetic variations. The Cas protein, an RNA-guided programmable nuclease, generates a double-strand break at precise genomic loci. However, the use of the clustered regularly interspersed short palindromic repeats (CRISPR)-Cas system to distinguish between single-nucleotide variations is challenging. The promiscuity of the guide RNA (gRNA) and its mismatch tolerance make allele-specific targeting an elusive goal. This review presents a meta-analysis of previous studies reporting position-dependent mismatch tolerance within the gRNA. We also examine the conservativity of the seed sequence, a region within the gRNA with stringent sequence dependency, and propose the existence of a subregion within the seed sequence with a higher degree of specificity. In addition, we summarize the reports on high-fidelity Cas nucleases with improved specificity and compare the standard gRNA design methodology to the single-nucleotide polymorphism (SNP)-derived protospacer adjacent motif (PAM) approach, an alternative method for allele-specific targeting. The combination of the two methods may be advantageous in designing CRISPR-based therapeutics and diagnostics for heterozygous patients.
