Maternal cardiovascular health and offspring neurodevelopment within the first five years of life: a birth cohort study.
Article in World journal of pediatrics : WJP, 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
backgroundThe first five years of life are sensitive periods for neurodevelopment. Poor maternal metrics of cardiovascular health may influence offspring neurodevelopment. Previous studies focused only on one or two metrics, or different time window. This study is aimed to investigate the effects of combined cardiovascular health metric exposure during pregnancy on the neurodevelopment of offspring during crucial periods.
methodsA total of 1007 mother‒child pairs recruited from 2013 to 2016 from the Shanghai Birth Cohort were included. Five maternal cardiovascular health metrics at 28 weeks of gestation were collected. Offspring neurodevelopment at 2-3 years and 4-5 years was evaluated with the Bayley-III and Wechsler preschool and primary scale of intelligence, fourth edition (WPPSI-IV), respectively.
resultsAfter adjusting for confounders, the scores for cognition and language at 2-3 years significantly increased by 1.63 [95% confidence interval (CI) 0.42-2.83, P = 0.008] and 0.84 (95% CI 0.005-1.67, P = 0.049) per one-point higher maternal cardiovascular health score, respectively. After false discovery rate adjustment, the associations were preserved in the cognitive domain. Similarly, each one-point higher maternal cardiovascular health score was associated with an increase of 0.92 (95% CI 0.16-1.68, P = 0.018) and 0.71 (95% CI 0.01-1.40, P = 0.047) in the visual space index and working memory index scores at 4-5 years, respectively, but with an false discovery rate-adjusted P > 0.05; in the sex-stratified analysis, the visual space index scores significantly increased (β = 1.47, 95% CI 0.38-2.56, P = 0.009), regardless of false discovery rate correction. In addition, each one-point higher maternal cardiovascular health score reduced the relative risk of suboptimal development in the visual space index domain by 0.83 (95% CI 0.70-0.99; P = 0.041) in female offspring despite the non-significant after false discovery rate adjustment.
conclusionsOur study provides novel evidence that maternal cardiovascular health during pregnancy is associated with offspring neurodevelopment within the first five years of life and that female offspring appear to derive greater benefit from higher maternal cardiovascular health scores. The potential role of maternal cardiovascular health in identifying risk of neurodevelopmental delay in clinical practice needs to be further explored.
