1 · What the graph read from it

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.

2 · The registry

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

We report the case of a 26-year-old woman with genetically confirmed Dravet syndrome (DS) who experienced atypical neurological deterioration in early adulthood, despite a previously stable clinical course. Her early history met the classical DS criteria, with the onset of febrile and afebrile seizures in infancy, followed by myoclonic, focal, and absence seizures, as well as developmental delay. Beginning at age 20, however, she developed new symptoms, including progressive tremor, postural instability, frequent gelastic-like seizures, and dysphagia severe enough to require temporary nasogastric feeding. Neuroimaging revealed basal ganglia and thalamic calcifications that had not been present in childhood. Mitochondrial evaluation demonstrated a mild reduction in oxygen consumption, despite normal enzyme activity. Genetic analysis, performed for the first time in adulthood, identified a previously unreported de novo missense variant in
