Presumed etiology of preterm birth: brain injury and neurodevelopmental outcomes.
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 2 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
aimTo determine the relationship between presumed preterm birth (PTB) etiology and the incidence of brain injury, and neurodevelopmental outcomes at 3 and 4.5 years. SUBJECTS AND
methodsProspective cohort study including 222 neonates born at 24-32 weeks' gestation. The presumed PTB etiology was defined by placental histopathology and other clinical features. Outcome measures included brain injury defined on MRI, neurodevelopmental outcomes using the Bayley Scales of Infant and Toddler Development, the Movement Assessment Battery for Children, Wechsler Preschool and Primary Scale of Intelligence, Beery Buktenica Developmental Test of Visual-Motor Integration.
resultsPresumed PTB etiology was inflammatory in 85 (38%), vascular in 57 (25%), multiple gestation in 56 (25%) and idiopathic in 24 (11%) neonates. Cognitive outcome at 3 years was marginally lower in the inflammatory group (Beta = -6.2, P = 0.05) relative to multiple gestation. At 4.5 years, white matter injury was associated with significantly lower motor scores (P = 0.004) and there were no significant associations between PTB etiology and WPPSI-III IQ scales or MABC-2 scores.
conclusionsThe lack of association between presumed PTB etiology (using integrated clinical phenotype and placental pathology) and cognitive/motor outcomes suggests that postnatal morbidities and brain injury are pivotal in the neurodevelopmental trajectory of these infants. IMPACT: The presumed etiology of preterm birth (PTB), based on placental histopathology and clinical features, does not predict long-term neurodevelopmental outcomes, such as cognitive scores at 4.5 years. Postnatal factors, including neonatal morbidities (e.g., bronchopulmonary dysplasia, retinopathy of prematurity, brain injury), are more significant in determining neurodevelopmental outcomes than the initial PTB cause. Placental histopathology helps identify PTB causes but shows no direct link to brain injury or neurodevelopmental outcomes. Infants with "idiopathic" PTB (no clear cause) have the greatest white matter injury burden, suggesting genetic or unrecognized factors.
