Ovarian response in preimplantation genetic testing for myotonic dystrophy type 1.
Observational study in Journal of assisted reproduction and genetics, 2025. 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
purposeTo evaluate ovarian stimulation response in couples undergoing preimplantation genetic testing (PGT-M) for myotonic dystrophy type 1 (DM1)
methodsRetrospective, observational, multicentric study. Parameters of ovarian response and PGT-M outcomes were compared according to the DM1-affected patient (female or male). A total of 229 couples underwent at least one controlled ovarian hyperstimulation cycle for the PGT-M procedure. Overall, 678 COS cycles were started, leading to 560 cycles with oocyte retrievals and subsequent PGT-M analysis.
resultsAt the time of the first PGT-M attempt, affected DM1 females were 1 year older and their serum AMH level was significantly lower than that of the healthy partner of affected DM1 males. After higher starting and total doses of exogenous gonadotropins, the number of mature oocytes was not statistically different between both groups (9 [6-13] vs 9 [6-13] mature oocytes, p=0.73). The FORT index was similar in both groups (35.2% [19.2-52.8] vs 33.3% [19.6-50.0], p=0.09), suggesting that antral follicle responsiveness to FSH is not altered. The live birth rate per fresh embryo transfer was 23.8% in the affected females group and 27.6% for the affected males.
conclusionAfter adapted controlled ovarian stimulation protocol and starting dose, a similar response (number of mature oocytes) and sensitivity (FORT index) was observed in DM1 females when compared to healthy partners of DM1 males undergoing PGT-M.
