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

backgroundVariants in the ATP6V0A1 gene, which encodes the α1 subunit of the V0 domain of the V-ATPases, are associated with developmental and epileptic encephalopathy 104 (DEE104). This study aimed to characterize the clinical features of a Chinese patient with ATP6V0A1 variants and facilitate the early diagnosis and treatment. CASE PRESENTATION: We report a case of a 13-month-old Chinese girl with DEE who presented with developmental delay, acute onset of clustered focal seizures, and status epilepticus. Physical examination revealed hypotonia and microcephaly. Brain MRI showed mildly enlarged bilateral lateral ventricles, a thin corpus callosum, and progressive cerebral atrophy. Genetic analysis identified a de novo missense mutation in the ATP6V0A1 gene (c.2222G > A, p.R741Q). While her epilepsy was refractory to multiple antiepileptic drugs, her seizures were controlled effectively with oxcarbazepine (OXC).

conclusionsWe identified a patient with DEE104 carrying a de novo ATP6V0A1 mutation, whose clinical presentation included developmental delay, clustered focal seizures, and status epilepticus. Our findings provide further support for considering OXC in the management of ATP6V0A1-related epilepsy.
