Early predictors of cognitive trajectories from birth to adolescence in children born extremely preterm.
Article in Developmental medicine and child neurology, 2026. 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
aimTo predict trajectories of cognitive abilities from ages 2 years to 15 years in children born extremely preterm.
methodThis longitudinal cohort study examined 659 (330 males) children born at 23 weeks to 27 weeks' gestation with cognitive assessments at ages 2 years, 10 years, and 15 years. Early factors analysed included maternal and neonatal characteristics, comorbidities, and neonatal inflammatory proteins.
resultsFor verbal, non-verbal, and combined cognitive abilities, greater social disadvantage at birth, male sex, 23 weeks to 24 weeks gestational age, bronchopulmonary dysplasia (BPD), ultrasound-detected cerebral white matter injury (WMI), and elevated inflammatory proteins in neonatal blood were associated with lower scores over the 15-year time frame for all outcomes. Analyses of joint association between socially disadvantaged groups and WMI suggested that the effect of no social disadvantage was evident only among children without WMI, whereas the effect of WMI was evident irrespective of social disadvantage.
interpretationIn this cohort of children born extremely preterm, social disadvantage at birth, male sex, BPD, WMI, and neonatal systemic inflammation were associated with slower gains in cognitive scores from age 2 years to 15 years. Early WMI moderated the associations between social disadvantage and cognitive functioning. Efforts to address both neonatal morbidities and social factors could improve cognitive functioning in children born extremely preterm.
