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

CRISPR-Cas9 has quickly become the method of choice for genome editing, with multiple publications describing technical advances and novel applications. It has been widely adopted as a tool for basic research and has significant translational and clinical potential. However, its usage has outpaced the establishment of essential and rigorous controls for unwanted off-target effects, manifested as small mutations, large deletions of target loci, or large-scale chromosomal rearrangements. A common application of CRISPR-Cas9 is as a tool for creating isogenic cell-line models to study the effects of precise mutations, or variants, on disease traits. Here, we describe the effect of standard CRISPR-Cas9 mutagenesis protocols on well characterized cancer cell lines. We demonstrate that commonly used methods for detecting correctly mutated clones fail to uncover large-scale rearrangements. We show that simple cytogenetic methods can be used to identify clones carrying chromosomal abnormalities and large mutations at target loci. These methods are quick and cost-efficient, and we suggest that such controls should be performed prior to publication of studies based on novel CRISPR-Cas9 mutated cancer cell lines.
