Screening of in vitro-produced cattle embryos to assess incidence and characteristics of unbalanced chromosomal aberrations.
Article in JDS communications, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
In cattle, pregnancy rates of in vitro-produced embryos are lower than those of in vivo-produced embryos. One of the reasons may be the increase in chromosomal aberrations due to in vitro maturation and fertilization of the oocyte. Currently, embryo transfer is commonly applied in nucleus cattle breeding programs, and the embryos are genotyped for genomic selection. Therefore, intensity data from SNP arrays can be exploited for preimplantation genetic testing by screening the intensity data of the embryos for unbalanced chromosomal aberrations. A total of 558 stage 8 Dutch Holstein embryos genotyped with SNP arrays were screened in an observational study in retrospect. We found a 5% incidence rate of unbalanced chromosomal aberrations (aneuploidy and ploidy issues) among 430 successfully genotyped cattle embryos. The 22 affected embryos showed either aneuploidy or ploidy issues; monosomy was most frequently observed (14/22). In most cases (16/19) the maternal chromosome or chromosomes were lost or gained. One of the monosomy cases gave rise to a live-born fully diploid individual, suggesting mosaicism. Given that embryo genotypes are readily available, monitoring incidence can easily be applied. Moreover, selection for euploid embryos may improve pregnancy rates for in vitro embryo transfer.
