General ability and specific cognitive functions are lower in children with epilepsy after perinatal ischemic stroke.

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
Introduction: Epilepsy develops in one third of children after perinatal stroke. Both epilepsy and stroke may be risk factors for impaired cognitive abilities. How the development of epilepsy is related to the cognitive profile of children with perinatal stroke is still unclear. The aim of the study was to evaluate general and specific cognitive functions in children with epilepsy and children without epilepsy after perinatal ischemic stroke. Methods: The study group consisted of 51 children with perinatal ischemic stroke confirmed by magnetic resonance imaging: 27 (53%) children with arterial ischemic stroke and 24 (47%) with periventricular venous infarction. Magnetic resonance imaging and electroencephalography were performed in all patients after the neonatal period. Epilepsy was diagnosed if the child had at least two unprovoked seizures occurring >24 h apart or one unprovoked seizure with a high recurrence risk. Cognitive assessments were performed using the Kaufman Assessment Battery for Children, Second Edition, at the age of ≥7 years. General ability (Fluid Crystallized Index, Mental Processing Index, Non-verbal Index) and specific cognitive functions (sequential processing, simultaneous processing, learning, planning, knowledge) were evaluated. Results: At the median age of 19.3 years (interquartile range 14.0-22) at the time of follow-up for epilepsy, 14 (27.5%) patients had developed epilepsy, and 37 (72.5%) patients were without epilepsy. All general cognitive ability scores were lower in children with epilepsy compared to children without epilepsy. Among specific cognitive functions, simultaneous processing, planning, and knowledge were lower in children with epilepsy compared to children without epilepsy: simultaneous processing mean [78.5, 95% CI: [69.8, 87.2], vs. 96.9, 95% CI [90, 103.9], Conclusion: Children with epilepsy after perinatal ischemic stroke have lower general cognitive abilities compared to children without epilepsy. The profile of the subscales indicates lower verbal abilities and executive functions in children with epilepsy. Children with post-stroke epilepsy need targeted cognitive monitoring for early aimed rehabilitation and for establishing an adapted learning environment.
