Risk Factors Influencing Neurodevelopmental Outcome and Survival in Preterm Infants: A Prospective Cohort Study.
Article in Children (Basel, Switzerland), 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
BACKGROUND/
objectivesSurvival of infants born very preterm or with very low birth weight has improved without a comparable reduction in neurodevelopmental morbidity, and the exposures acting during neonatal intensive care are usually studied in isolation. We aimed to identify which prenatal, perinatal and postnatal factors are independently associated, domain by domain, with neurodevelopment at 24 months' corrected age (CA) and with the composite outcome of neurodevelopment and survival.
methodsSingle-centre prospective cohort of 146 infants (135 assessed at 24 months' CA and 11 who died between day 8 of life and the assessment) with gestational age ≤ 32 weeks and/or birth weight ≤ 1500 g admitted to a level III unit (2018-2022). Neurodevelopment was assessed with the Bayley-III; a score < 85, rather than the conventional <70 being taken as pathological, was used, with the third edition yielding systematically higher scores. Eighty-one candidate exposures were screened; for each domain a primary composite outcome (score < 85 or death) and a secondary survivors-only outcome were analysed by exploratory multivariable logistic regression.
resultsTwenty-nine of 164 eligible survivors (17.68%) were lost to follow-up and did not differ appreciably from the analysed cohort (all standardised differences ≤ 0.10). Severe intraventricular haemorrhage was associated with language, sepsis and anaemia requiring transfusion with motor, and male sex and sepsis with socio-emotional development, whereas no covariate was associated with cognition. No nutritional, metabolic or postnatal-growth variable was independently associated with any domain, and no association survived Benjamini-Hochberg control of the false discovery rate (optimism-corrected c-statistics 0.598-0.739).
conclusionsThese findings are associations rather than evidence of causality; they are hypothesis-generating and warrant multicentre external validation and longer follow-up.
