Association between sleep duration at 12 and 18 months and epilepsy risk at 2-3 years: the Japan Environment and Children's Study.

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
backgroundSleep deprivation has notable effects on neurobehavioural functioning in children. However, the link between sleep duration and the risk of developing epilepsy in early childhood remains uncertain. The aim of this study was to explore the association between sleep duration at 12 and 18 months and the risk of epilepsy at 2 and 3 years of age.
methodsData from the Japan Environment and Children's Study (JECS), a largescale birth cohort, were analysed. We assessed the risk of epilepsy at 2 and 3 years of age among children sleeping under 11 hours per night, the minimum recommended by the American Academy of Sleep Medicine for 1-2 year olds.
resultsOverall, 86 441 children were retrospectively analysed. Of these, 8786 (10.2%) and 12 850 (14.9%) slept for less than 11 hours at 12 months and 18 months, respectively. Multivariate logistic regression showed that a sleep duration of less than 11 hours at 12 months remained significantly associated with epilepsy incidence at 2 and 3 years (adjusted OR (aOR) 2.02, 95% CI 1.01 to 4.01, p=0.045; aOR 1.98, 95% CI 1.15 to 3.41, p=0.013). Furthermore, a sleep duration of less than 11 hours at 12 and 18 months was significantly associated with epilepsy incidence at 3 years (aOR 2.77, 95% CI 1.28 to 6.01, p=0.010).
conclusionsInsufficient sleep in infancy may be linked to epilepsy later in childhood. These findings highlight the importance of sleep interventions during early life to improve long-term neurological health.
