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

Current dual base editors and hypermutators exhibit limited types of base conversion and constrained mutational diversity. To address this challenge, we engineer a compact dual base editor "A&GBE" by fusing a deaminase and glycosylase with nickase Cas9 (nCas9) to enable concurrent adenine and cytosine editing. Furthermore, we develop quadruple base mutating modules (QBMM) by fusing nickase or dead Cas9 with engineered thymine-DNA glycosylase (TDG), N-methylpurine DNA glycosylase (MPG) and TadA8e, together with MS2-MCP system recruited activation-induced cytidine deaminase (AID). This QBMM enables simultaneous mutation of all four types of nucleotide bases (A, T, G, C) within an approximately 100 base pair (bp) sequence surrounding the gRNA target site. This platform generates hyper diverse multi-nucleotide variants, establishing a powerful tool for accelerated protein evolution, functional genomics, and disease modeling.
