Zona pellucida treatment before CRISPR/Cas9-mediated genome editing of porcine zygotes.
Article in Veterinary medicine and science, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundIncreasing the permeability of the zona pellucida (ZP) of oocytes before CRISPR/Cas9 electroporation may improve the efficiency of gene editing; however, the effects of this approach on subsequent developmental processes are unclear. In this study, the effects of ZP treatment before electroporation on embryonic development and gene editing in porcine embryos were evaluated.
methodsThe ZP of zygotes was weakened or removed by exposure to 0.5% actinase E, followed by electroporation of the Cas9 protein with guide RNA targeting GGTA1.
resultsThe blastocyst formation rate of ZP-free zygotes after electroporation was significantly lower (p < 0.05) than that of ZP-intact zygotes. The mutation rate in blastocysts from ZP-weakened zygotes was similar to that in ZP-intact zygotes, whereas ZP removal increased the mutation rate. The mutation efficiency in blastocysts from electroporated zygotes did not differ among ZP treatment groups.
conclusionsOur results indicate that weakening the ZP does not affect the developmental competence, mutation rate, or mutation efficiency of electroporated zygotes, whereas ZP removal has a detrimental effect on embryonic development but may increase the mutation rate.
