Prevalence and Temporal Trends of Epilepsy in Children: A Retrospective Birth Cohort 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
objectiveEpilepsy is one of the most common chronic neurologic diseases in children; however, few recent studies examine the prevalence of epilepsy and its evolution over time according to birth or maternal characteristics. The aim of the study was to examine the prevalence of epilepsy in children born between 2002 and 2020 and the temporal trends by year of birth, in Ontario, Canada, overall, and according to maternal and birth characteristics.
methodsWe included all in-hospital deliveries between 2002 and 2020 (N = 2,343,482) in Ontario, Canada, using linked administrative health dataset. We estimated the overall prevalence of epilepsy diagnosed before the age of 18 years, by birth and maternal characteristics. For temporal trend analyses, we restricted our population to children born up to 2012 (N = 1,405,271) and examined the prevalence of epilepsy diagnosed by age 8 by their year of birth, using Poisson regression.
resultsThe overall prevalence of epilepsy in our cohort was 8.1 per 1,000 live births (95% CI: 8.0-8.2). Prevalence was higher for boys, for children born preterm, with congenital malformations, from multiple pregnancies, from mothers born in Canada, and for children living in deprived areas. Epilepsy prevalence diagnosed by age 8 increased slightly between 2002 and 2012 cohorts (6.9 [95% CI: 6.2-7.6] to 7.3 [95% CI: 6.6-8.1] per 1,000 live births, respectively). Differences by gestational age as gradient and socioeconomic characteristics were persistent and stable over time, while those by pregnancy plurality and sex decreased. SIGNIFICANCE: In a large population-based birth cohort in Canada, we observed a slight increase in epilepsy prevalence over time among children born in 2002 and those born in 2012 and persistent disparities by gestational age, socioeconomic position, and maternal immigration status. This study highlights the need for continued surveillance of rates to see if this increasing trend is persistent, to understand the potential causes behind it, and to understand the persistence of these disparities.
