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

Deaminase fused-Cas9 base editing technologies have enabled precise single-nucleotide genomic editing without the need for the introduction of damaging double-stranded breaks and inefficient homology-directed repair. However, current methods to isolate base-edited cell populations are ineffective, especially when utilized with human pluripotent stem cells, a cell type resistant to genome modification. Here, we outline a series of methods that employ transient reporters of editing enrichment (TREE) to facilitate the highly efficient single-base editing of human cells at precise genomic loci. Briefly, these transient reporters of editing enrichment based methods employ a transient episomal fluorescent reporter that allows for the real-time, flow-cytometry-based enrichment of cells that have had single nucleotide changes at precise genomic locations. This protocol details how these approaches can enable the rapid (~3-4 weeks) and efficient (clonal editing efficiencies >80%) generation of biallelic or multiplexed edited isogenic hPSC lines using adenosine and cytosine base editors.
