Cytogenetic and Microarray Analysis Follow-Up of PGT-A Mosaic and Sex Discrepant Embryos During Pregnancy: Absence of Confirmation and Follow-Up Recommendations.
Article in Prenatal diagnosis, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesThe objective of this study was to examine the concordance of results between mosaic pre-implantation genetic testing for aneuploidy (PGT-A) and diagnostic testing in resulting pregnancies conceived by IVF with PGT-A.
methodsThis study retrospectively provides analysis of 328 patients ascertained due to a mosaic PGT-A finding and 25 with a discordant reported sex, studied prenatally, utilizing standard karyotype and/or SNP microarray analysis.
resultsNone of the 328 mosaic PGT-A findings were confirmed by the diagnostic prenatal studies with karyotype and/or microarray analysis. Additionally, of the 298 prenatal microarray studies performed, five demonstrated pathogenic abnormalities (1.7%) that were unrelated to PGT-A referral. Thirty-four of these cases were also studied to determine if UPD occurred; all were biparental.
conclusionsThis work emphasizes the importance of PGT-A follow-up and demonstrates that the vast majority will have normal diagnostic results and only a small number will be confirmed using prenatal diagnostic analysis. This work also suggests the most efficient way to proceed with diagnostic follow-up studies. Additionally, it shows the importance of fetal sex confirmation in all normal PGT-A studies.
