The connection between neonatal jaundice and neurodevelopment later in life: a national birth cohort study.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundElevated serum bilirubin in neonates may serve as an early indicator of later neurodevelopment after birth. This study examined the connection between neonatal jaundice requiring phototherapy and later neurodevelopment.
methodsThis retrospective population-based cohort included 3,203,983 children born in Korea from 2009 to 2015, tracked from birth until December 2021 in Korea. Neurodevelopmental outcomes at 66-71 months of age were assessed using national child health screening data. Analyses controlled for confounders including sex, birth weight, prematurity, chromosomal abnormalities, congenital malformations, income, and infant feeding type. Neurodevelopmental outcomes were evaluated in six domains (gross motor, fine motor, cognition, language, social skills, and self-help) using the Korean Developmental Screening Test (K-DST). Effect of phototherapy duration on each domain was also examined.
resultsA total of 1,004,385 neonates were included, of whom 121,366 (56.0% male) received phototherapy. Neonatal jaundice requiring phototherapy was significantly associated with abnormal outcomes in gross motor (adjusted odds ratio [aOR] 1.087, 95% CI 1.049-1.127, P < 0.0001), cognition (aOR 1.045, 95% CI 1.013-1.077, P = 0.0052), and language (aOR 1.049, 95% CI 1.013-1.086, P = 0.0072). Longer phototherapy duration (≥ 5 days) was associated with abnormal outcomes in overall assessment and gross motor, fine motor, cognition, and language domains.
conclusionsNeonatal jaundice requiring phototherapy was associated with higher risk of abnormal neurodevelopment at age six, particularly in gross motor, cognition, and language domains. Prolonged phototherapy was also linked to adverse outcomes.
