Adverse long-term outcomes following seizures in non-asphyxiated term infants: A population-based 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
backgroundWhile birth asphyxia is a well-established cause of neonatal seizures associated with adverse outcome, less is known about outcomes after seizures in non-asphyxiated infants. We investigated adverse outcomes following neonatal seizures in infants born vigorous and without evidence of asphyxia.
methodsSwedish national cohort (2009-2015) including 656,088 live-born term vigorous infants. The exposure was a diagnosis of neonatal seizure. A combined adverse outcome included any diagnosis of cerebral palsy, epilepsy, intellectual and developmental disability, or death. Hazard ratios (HR) with 95% confidence intervals (CI) were calculated.
results470 infants were diagnosed with seizures, and 299 (64%) had EEG-verified seizures. Among those with the combined adverse outcome, 75% were diagnosed the first year, corresponding to an incidence of 178 per 1000 of all infants and 224 per 1000 among EEG-verified cases. The one-year incidence rates were 220 per 1000 child years for all, and 283 per 1000 child years among those EEG-verified compared to 2.3 per 1000 child years without seizures. The HR for all seizures within 1 year was 95 (77-120), and for EEG-verified seizures 120 (96-160).
conclusionThis study demonstrates a strong association between neonatal seizures and adverse long-term outcome in vigorous term infants without asphyxia. IMPACT: Term infants who were vigorous and non-asphyxiated at birth but later developed neonatal seizures faced a significant elevated risk of adverse outcomes, including death, cerebral palsy, epilepsy, intellectual and developmental disabilities. Among these adverse outcomes epilepsy was the most frequent and was predominantly diagnosed during the first year of life. Population-based studies utilizing national health and quality registers can greatly enhance our understanding of long-term outcomes following neonatal seizures.
