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 and base editors (BEs) systems are poised to become the gene-editing tool of choice in clinical contexts; however, large-fragment deletion was found in Cas9-mediated mutation cells and mice. In this study, by analyzing 16 gene-edited rabbit lines (including 112 rabbits) generated using SpCas9, BEs, xCas9, and xCas9-BEs with long-range PCR genotyping and long-read sequencing by the PacBio platform, we show the extension of thousands of base fragment deletions in single-guide RNA/Cas9 and xCas9 system mutation rabbits, but no deletions were found in BE-induced mutation rabbits. Thus, we first validated that no large-fragment deletion was induced by the BEs system, suggesting that BE systems can be beneficial tools for the further development of highly accurate and secure gene therapy for the clinical treatment of human genetic disorders.
