A deep dive into the morphokinetics and ploidy of low-quality blastocysts.
Article in F&S reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Objective: To describe morphokinetic parameters and ploidy among low-quality blastocysts not meeting the criteria for clinical use. Design: Prospective cohort study. Setting: Academic medical center. Patients: Two hundred patients undergoing in vitro fertilization between February 2018 and November 2019. Interventions: All embryos were cultured in a time-lapse incubator. All expanded blastocysts underwent preimplantation genetic testing for aneuploidy using next-generation sequencing. Main Outcome Measures: Static blastocyst morphology grading; morphokinetic parameters, including time to each cell division (2-cell formation to 8-cell formation); time to morula formation; time to the start of blastulation; time to blastocyst formation; and preimplantation genetic testing for aneuploidy results. Results: A total of 1,306 embryos progressed to the expanded blastocyst stage; of these, 935 embryos met the criteria for clinical use and were designated as high quality, whereas 371 embryos were graded as low quality and did not meet the criteria for use. In morphokinetic evaluation, low-quality embryos developed more quickly to 5-cell formation (t5) 48.4 [42.4-48.7) vs 50.2 [46.3-50.1] hours, but progressed more slowly thereafter with tM 91.5 [85.9-92.3] vs 88.3 [82.1-88.3] and tB 114.0 [106.4-113.9] vs 106.9 [101.3-107.4] hours. Among the low-quality embryos, 75.5% were aneuploid, 22.4% were euploid, and 2.2% had undetermined chromosome copy number results. Morphokinetic parameters did not differ between the euploid and aneuploid low-quality embryos. Conclusions: Morphokinetic analysis did not distinguish between euploid and aneuploid low-quality embryos.
