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

Induced pluripotent stem cells (iPSCs) generated from patients are a valuable tool for disease modelling, drug screening, and studying the functions of cell/tissue-specific genes. However, for this research, isogenic iPSC lines are important for comparison of phenotypes in the wild type and mutant differentiated cells generated from the iPSCs. The advent of gene editing technologies to correct or generate mutations helps in the generation of isogenic iPSC lines with the same genetic background. Due to the ease of programming, CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)-Cas9-based gene editing tools have gained pace in gene manipulation studies, including investigating complex diseases like cancer. An iPSC line with drug inducible Cas9 expression from the Adeno-Associated Virus Integration Site 1 (AAVS1) safe harbor locus offers a controllable expression of Cas9 with robust gene editing. Here, we describe a stepwise protocol for the generation and characterization of such an iPSC line (AAVS1-PDi-Cas9 iPSC) with a doxycycline (dox)-inducible Cas9 expression cassette from the AAVS1 safe harbor site and efficient editing of target genes with lentiviral vectors expressing gRNAs. This approach with a tunable Cas9 expression that allows investigating gene functions in iPSCs or in the differentiated cells can serve as a versatile tool in disease modelling studies.
