Perinatal growth and neurodevelopmental outcomes in preterm infants conceived via assisted reproductive technology: a retrospective comparative cohort study.
Article 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. 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 aims to compare growth parameters and neurodevelopment outcomes between preterm infants conceived via assisted reproductive technology (ART) and those conceived spontaneously, with a focus on head circumference, length, weight, and developmental performance as assessed by the Gesell Developmental Scales.
methodsPropensity score matching was employed to balance baseline characteristics between groups. Post-matching comparisons were conducted for head circumference, length, and weight at birth, 1 month, and 3 months of age. Neurodevelopmental assessments were performed at 1, 2, and 3 years using the Gesell scales. After PSM, a total of 290 preterm infants were included in the final analysis, with 145 infants in each of the ART and non-ART groups, respectively.
resultsFollowing matching, baseline characteristics were comparable between the groups. At both 1 month and 3 months of age, ART-conceived infants group demonstrated significantly lower mean head circumference, length, and weight compared to infants conceived spontaneously. Additionally, ART-conceived infants demonstrated significantly lower developmental scores at 1 and 2 years of age (p < 0.05).
conclusionsPreterm infants conceived via ART exhibited comparatively lower growth metrics developmental scores during early infancy compared to their spontaneously conceived counterparts. These findings highlight the importance for proactive clinical monitoring and targeted early interventions to support optimal outcomes in this population.
