Effect of Blastocyst Morphology and Developmental Rate on Euploidy and Live Birth Rates in PGT-A Cycles: A 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
This study was to evaluate the relationship between morphology or developmental rate of blastocysts and ploidy status in preimplantation genetic testing for aneuploidy (PGT-A) cycles, or live birth rates in single euploid frozen-thawed embryo transfer (FET) cycles. We focused on infertile patients who underwent PGT-A procedures, following with single euploid FET cycles in the assisted reproduction center from January 2016 to December 2022. Blastocysts were categorized for biopsy, and euploid embryos would be selected for transfer. Multivariate logistic regression was used to assess the effects of blastocoel expansion degree, inner cell mass (ICM) and trophectoderm (TE) grades and developmental stage (Day 5, 6 and 7) on euploidy and live birth rates. A total of 4172 blastocysts from 941 PGT-A cycles were included. Expansion 4 were associated with lower euploidy rate than expansion 5 (P = 0.011) and 6 (P = 0.001). Better ICM (P < 0.05 for A compared to B grade) increased blastocyst euploidy. Euploidy rate was significantly associated with A grade TE (P < 0.001). However, no relationship existed between blastocyst euploidy and developmental rate. Furthermore, live birth rates had no significant effect on most of morphological parameters in euploidy blastocyst FET cycles, only A grade TE was shown higher live birth rate than C grade (P = 0.024). The rate of euploidy in morphologically poor blastocysts is low in the cohort, but the developmental rate does not associate with euploidy. Moreover, only TE grades take association with live birth rates, when the single euploidy blastocyst was transplanted.
