Electrographic-only seizures and status epilepticus in neonates with Tuberous Sclerosis Complex.

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
backgroundTuberous Sclerosis Complex (TSC) is a multisystem human genetic disorder frequently associated with early-onset epilepsy. Neonatal seizures are increasingly recognized. Detailed neonatal electroclinical characterization remains limited.
methodsWe conducted a multicentre retrospective study across 16 Italian centres, including 32 neonates (term and preterm) with definitive diagnosis of TSC and at least one EEG- or video-EEG-confirmed seizure during neonatal period. Seizure semiology, EEG features, clinical variables were systematically reviewed and analysed.
resultsNeonatal seizures were recorded at a mean postnatal age of 8.7 ± 9.9 SD days and a mean postmenstrual age of 39.4 weeks, significatively earlier in preterm VS term newborns (respectively 36,5 ± 1,7 SD and 40,4 ± 1,9 SD; p < .001). Electrographic-only seizures were the most frequent, reported in 58%. Status epilepticus was recorded in 31% of neonates. Interictal EEG abnormalities were present in 83% of infants, while in 17%, seizures occurred without preceding interictal discharges. TSC2 was the predominant gene involved (93%).
conclusionEpilepsy in TSC may present in neonatal period as electrographic-only seizures, including status epilepticus, and may occur before term age. This underscores the importance of early EEG monitoring -even in asymptomatic neonates with suspected or confirmed TSC- to enable timely diagnosis and intervention. IMPACT: The study shows that neonatal‑onset epilepsy is a key early manifestation of TSC, often presenting as electrographic‑only seizures and sometimes as status epilepticus, especially in infants with TSC2 variants. It adds a detailed multicentre electroclinical description demonstrating that seizures may occur before term age, are frequently clinically silent, and interictal epileptic discharges are not always present at seizure onset. It highlights the need for early EEG monitoring in all neonates with suspected or confirmed TSC, to enable timely detection of seizures and intervention.
