Intrauterine exposure to maternal diabetes and the risk of developing epilepsy in children: a national cohort study of 2.3 million children.

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
backgroundApproximately half of the epilepsy cases lack a documented cause. Despite growing evidence linking maternal diabetes to pregnancy complications and impaired child neurodevelopment, little is known about its potential association with child epilepsy. This study aims to determine whether intrauterine exposure to maternal pre-existing type 1 diabetes mellitus (T1DM), type 2 diabetes mellitus (T2DM), or gestational diabetes mellitus (GDM) increases the risk of epilepsy in children.
methodsThis study included live-born children without major malformations in Sweden from 1998 to 2021. Children were followed from birth until epilepsy diagnosis, death, emigration, or October 2023. Child epilepsy, maternal T1DM, T2DM, GDM, and a comprehensive set of covariates were identified through linked national health registers. Multivariable Cox proportional hazards regression was used to examine the association between maternal diabetes and child epilepsy, estimating adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs). Analyses also included paternal T1DM and T2DM as negative control exposures to assess potential genetic confounding. Preeclampsia, preterm birth, and birth asphyxia were evaluated as mediators, using a sequential mediation approach.
resultsOf the 2,305,051 children, 14,283 (0.6%) were exposed to maternal T1DM, 3,833 (0.2%) to T2DM, and 36,388 (1.6%) to GDM. Over a median follow-up of 13 years (range 0 to 25.8 years), 18,968 were diagnosed with epilepsy, corresponding to an incidence rate of 63.7 per 100,000 person-years. Compared with no maternal diabetes, maternal T1DM and T2DM were associated with increased hazards of epilepsy in children, with aHRs of 1.30 (95% CI 1.11-1.52) and 1.41 (95% CI 1.01-1.97), respectively. Preterm birth and birth asphyxia jointly mediated nearly half of the total effect of T1DM (HR
conclusionsIn this large cohort study, maternal T1DM and T2DM were associated with an increased risk of epilepsy in children. These associations are likely influenced by intrauterine mechanisms and were partially mediated by preterm birth and asphyxia-related conditions at birth.
