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.
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
Prime editing is a genome engineering tool that allows installation of various small edits with high precision. However, prime editing efficiency and purity can vary widely across different edits, genomic targets, and cell types. Prime editing typically offers more precise editing outcomes compared to other genome editing methods such as homology-directed repair. However, it can still result in significant rates of unintended editing outcomes, such as indels or imprecise prime edits. This issue is particularly notable in systems utilizing a second nicking gRNA, such as PE3 and PE5, as well as in dual pegRNA systems and fully active nuclease systems such as PEn, which increase efficiency but compromise precision. In this work, we show that pharmacological inhibition of DNA-PK and Polϴ, two major mediators of mutagenic DNA repair pathways, improves precision of PEn, PE3, PE5, PE7, and dual pegRNA editing systems, including TwinPE, HOPE, and Bi-PE, across multiple genomic loci and edit types. We show that co-inhibition of DNA-PK and Polϴ mitigates both prime editing-unrelated indels and prime editing by-products such as template duplications. Moreover, in the case of PEn, this strategy also substantially improved the off-target editing profile. Together, our data establish small molecule modulation of DNA repair pathways as a general strategy to maximize the precision of diverse prime editing systems.
