Impact of early nutrition on brain development and neurocognitive outcomes in very preterm infants.
Article in Pediatric research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundMalnutrition of preterm infants may negatively affect brain growth and later neurocognitive function. We aimed to investigate the association between very preterm infants' macronutrient intakes, and brain MRI at term and neurodevelopment at 2 years.
methodsSingle-center, retrospective cohort including extremely (22-27w) and very (28-31w) preterm infants born 2011-2014. The intakes of fluid, protein, carbohydrate, fat, and total calories during days 0-28 together with body weights were assessed in relation to brain MRI (morphology, volumetry, diffusion-weighted imaging) at term, and cognition (BSID-III) at 2 years, using adjusted multivariable regression analyses.
resultsSeventy-two infants were included. A lower (p < 0.001) caloric intake in extremely preterm (n = 26) than in very preterm (n = 46) infants did not translate to any differences in brain volumes. While bivariate correlations (p < 0.01) were found between the enteral intakes of all macronutrients, and white matter volume and apparent diffusion coefficients, none of the correlations remained significant after adjusting for covariates in the multivariable analysis. Similarly, no associations between nutrient intakes and cognitive development remained after covariate adjustment.
conclusionIn a cohort of preterm infants receiving macronutrient intakes meeting current recommendations, individual variations in nutrition did not influence brain growth or neurodevelopment. IMPACT: Early postnatal macronutrient intake was not associated with brain volumes at term or neurocognitive outcomes at 2 years in very preterm infants All infants received nutritional intakes meeting current recommendations Adequate macronutrient intake based on a standardized protocol may eliminate the need for further minor adjustments in the pursuit of supporting brain growth and neurodevelopment in preterm infants.
