Impact of Laser-Assisted Hatching on Cognitive and Metabolic Development of Singletons Conceived Through Frozen-Thawed Embryo Transfer: A Matched Cohort Study.
Article in BJOG : an international journal of obstetrics and gynaecology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveThis study aimed to examine the impact of laser-assisted hatching (LAH) on the physical, metabolic, cognitive and behavioural profiles of singletons conceived through frozen-thawed embryo transfer (FET) at the preschool age.
designA matched cohort study.
settingThe reproductive centre of Women's Hospital, Zhejiang University School of Medicine. POPULATION: Singletons born to couples with infertility who underwent FET cycles with or without LAH treatment from 2016 to 2019 and were followed up till age 4-6 years in 2023.
methodsCognitive and behavioural development was evaluated at the preschool age using the Wechsler Preschool and Primary Scale of Intelligence, Fourth Edition (WPPSI-IV) and the Adaptive Behavior Assessment System, Second Edition (ABAS-II). Statistical analysis was performed using moderated multiple linear regression.
main outcome measuresThe full-scale intelligence quotient (FSIQ) and general adaptive composite (GAI).
resultsIn total, 120 pairs of mother and child were included in the analysis. No significant differences in age, sex, height, weight, body mass index, blood pressure, thyroid function and metabolic indicators were observed between the two groups. After adjusting for demographics and socioeconomic status, LAH singletons showed FSIQ and GAI scores similar to those of non-LAH singletons.
conclusionsAt 4-6 years of age, the cognitive, metabolic and physical developmental outcomes of preschool children born after LAH treatment were comparable with those of the non-LAH group, indicating that LAH may be considered a safe assisted reproductive technology method. However, further longer and regular follow-ups are needed to validate the findings of this study.
