The polygenic score for age at menopause is independently associated with the response of controlled ovarian hyperstimulation in women undergoing IVF.

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
backgroundWhile Anti-Müllerian hormone (AMH) helps personalise In Vitro Fertilization (IVF) stimulation protocols, a significant number of women still do not achieve an optimal ovarian response. To address this, we explore the utility of a polygenic score for age at natural menopause (ANM) as a predictor for ovarian response during IVF.
methodsThis cohort study included 435 women who underwent standardised IVF stimulation, and they were genotyped to calculate a polygenic score (PGS) for ANM. Linear regression and ANCOVA models were used to assess the associations between the PGS and ovarian response, oocyte and embryo quality and pregnancy rates, adjusting for genomic components and age.
findingsA one standard deviation increase in the PGS for ANM was associated with 0.950 (p < 0.001) additional follicles two days before ovum pick-up. While the PGS did not significantly associate with the overall diminished ovarian response (DOR), a mean difference of -0.33 (p < 0.01) in PGS was observed when comparing individuals with fewer than 8 follicles retrieved to those with an optimal ovarian response. No association was found between the PGS and ongoing pregnancy. Causal mediation revealed that the effect of the PGS onto the number of follicles was partly mediated by AMH levels (proportion mediated = 31%, p = 0.002).
interpretationA lower PGS for ANM, indicative for earlier menopause, is independently associated with a reduced ovarian response during IVF stimulation, specifically fewer follicles retrieved and mostly independent of AMH levels. This highlights the potential of ANM-related genetic variants to inform personalised IVF protocols by predicting ovarian responsiveness.
