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

Homology-directed repair (HDR)-mediated knock-in efficiency is a composite of double-strand break (DSB) induction and repair pathway selection during targeted insertion. Thus, optimization of HDR-mediated knock-in presents significant challenges. To address this, we employed a mouse embryonic stem cell-based triple-reporter platform to examine how donor design and experimental parameters are associated with DSB induction and the balance between HDR-mediated knock-in and end-joining-mediated targeted insertion (EJ-TI). Our analysis reveals that donor design directly impacts DSB induction: co-electroporation of donor plasmids with Cas9/gRNA reduced cleavage efficiency, and Homology-Independent Targeted Integration (HITI) sequences further reduced this efficiency, thereby biasing overall knock-in efficiency. When normalized to DSB levels, HITI increased total targeted insertion yield (knock-in + EJ-TI) with shorter arms and favored HDR-mediated knock-in over EJ-TI with longer arms. Conversely, under adeno-associated virus (AAV) donor conditions, HITI showed donor-format dependency. It increased knock-in and decreased EJ-TI only with a self-complementary AAV donor, but had little effect with a single-stranded AAV donor. These results highlight the importance of separately evaluating DSB induction, total targeted insertion yield, and the balance between HDR-mediated knock-in and EJ-TI using a triple-reporter platform when optimizing knock-in strategies.
