Differences in preimplantation blastocyst chromosomal aberrations between polycystic ovary syndrome women and controls: a multi-center retrospective cohort study.

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
purposeComprehensive chromosomal status of blastocyst from women with polycystic ovary syndrome (PCOS) was limited. This study aimed to identify possible differences in the preimplantation blastocyst chromosome aberrations between PCOS women and controls receiving preimplantation genetic testing (PGT).
methodsThis was a multi-center retrospective cohort study including a total of 707 blastocysts from 147 PCOS women and 3006 blastocysts from 821 control women receiving PGT between 2015 and 2021. Embryonic chromosomal aberration spectrums were compared between PCOS and controls. Mixed effects generalized linear model was conducted to explore possible influence of PCOS-related endocrinological disorders on embryonic chromosomal abnormalities.
resultsBlastocysts from PCOS demonstrated significantly lower aneuploidy rate (15.2% vs. 25.2% per women, P < 0.001; 14.7% vs. 25.4% per blastocyst, P < 0.001) but greater mosaicism rate (12.5% vs. 8.0% per women, P = 0.007; 16.5% vs. 8.7% per blastocyst, P < 0.001). Mixed effects generalized linear model identified PCOS as an independent protective factor against embryonic aneuploidy (adjusted odds ratio = 0.68, 95% confidence interval, 0.50-0.93, P = 0.014) but a risk factor for embryonic mosaicism (adjusted odds ratio = 1.52, 95% confidence interval 1.11-2.10, P = 0.009). Further model analysis suggested that insulin resistance could be responsible for the increased risk of embryonic mosaicism among PCOS women (adjusted odds ratio = 2.17, 95% confidence interval, 1.10-4.31, P = 0.026).
conclusionPCOS is associated with a lower aneuploidy risk but an increased mosaicism risk in preimplantation blastocysts, and insulin resistance should be investigated as a potential cause.
