Attaining neurodevelopmental milestones and exposures to fine particulate matter and environmental green spaces.
Article in Environmental health : a global access science source, 2026. 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
backgroundEarly-life environmental exposures may influence infant neurodevelopment. We examined associations between perinatal air pollution, green space exposure, and milestone attainment during the first two years.
methodsWe conducted a longitudinal population study of Flemish children born in 2018, using well-baby clinic data (n = 46,584). Outcomes were delay of six milestones within predefined windows assessed using the Dutch version of the Denver Developmental Screener, and the exact age at two milestones. Municipality-level PM2.5, PM10, and green space were assigned. Associations per interquartile-range (IQR) increase were estimated using multivariable logistic and linear regression with multiple imputation.
resultsPM2.5 was positively associated with delaying the milestone ‘Points at 6 body parts of a doll’ (OR = 1.13, 95% CI:1.04;1.22). PM10 was positively associated with delaying the milestones ‘Says sentences of 2 words’ (OR = 1.07, 95%CI:1.00;1.13), ‘Points at 6 body parts of a doll’ (OR = 1.11, 95%CI:1.05;1.18), and ‘Pulls up to standing position’ (OR = 1.11, 95%CI:1.02;1.22). Low green was significantly associated with a reduced odds of delaying the milestones ‘Says 2 sound-words with comprehension’ (OR = 0.89, 95%CI:0.85;0.93) and ‘Pulls up to standing position’ (OR = 0.87, 95%CI:0.81;0.94), and negatively associated with walking age in months (B=-0.094, 95%CI:-0.129;-0.059). High green was negatively associated with delaying the milestones ‘Says sentences of 2 words’ (OR = 0.96, 95%CI:0.94;0.99) and ‘Points at 6 body parts of a doll’ (OR = 0.93, 95%CI:0.89;0.96). Total green was negatively associated with delaying the milestones ‘Says 2 sound-words with comprehension’ (OR = 0.94, 95%CI:0.88;0.99) and ‘Points at 6 body parts of a doll’ (OR = 0.95, 95%CI:0.91;0.99), and also with walking age (B=-0.054, 95%CI:-0.089;-0.019).
conclusionPM exposure was linked to delays, while green space exposure showed a protective association. These findings support reducing PM10/PM2.5) and promoting green space exposures for child development.
