CRISPR/Cas9-mediated knock-in of the murine Y chromosomal genes Zfy1 and Zfy2.
Article in BMC genomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe Y-linked mouse zinc finger genes Zfy1 and Zfy2 are critical fertility factors in mice but the mechanisms by which they regulate spermatogenesis remain unclear. We recently produced Zfy1/2 double knock-out mice and observed a complete loss in fertility. However, the biochemical mechanism by which Zfy regulates spermatogenesis is unknown, and ZFY expression has not yet been confirmed at the protein level. As both Zfy homologues share ~ 95% sequence similarity, it is difficult to produce an anti-ZFY antibody specific to either homologue.
resultsTo overcome this technical challenge, we used CRISPR/Cas9 genome editing to develop tagged Zfy1 knock-in (XY
conclusionsThese novel knock-in mice can be used in future investigations to determine how ZFY controls spermatogenesis.
