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

Gene editing using CRISPR/Cas9 is a promising method to cure many human genetic diseases. We have developed an efficient system to deliver Cas9 into the adeno-associated virus integration site 1 (AAVS1) locus, known as a safe harbor, using lentivirus and AAV viral vectors, as a step toward future in vivo transduction. First, we introduced Cas9v1 (derived from Streptococcus pyogenes) at random into the genome using a lentiviral vector. Cas9v1 activity was used when the N-terminal 1.9 kb, and C-terminal 2.3 kb fragments of another Cas9v2 (human codon-optimized) were employed sequentially with specific single-guide RNAs (sgRNAs) and homology donors carried by AAV vectors into the AAVS1 locus. Then, Cas9v1 was removed from the genome by another AAV vector containing sgRNA targeting the long terminal repeat of the lentivirus vector. The reconstituted Cas9v2 in the AAVS1 locus was functional and gene editing was efficient.
