Vagus nerve stimulation combined with ketogenic diet versus ketogenic diet alone in the treatment of febrile infection-related epilepsy syndrome in children: efficacy and long-term prognosis 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
purposeTo evaluate the clinical efficacy and long-term functional prognosis of vagus nerve stimulation (VNS) combined with ketogenic diet (KD) in the treatment of children with febrile infection-related epilepsy syndrome (FIRES).
methodsA retrospective analysis was performed on inpatients with a diagnosis of FIRES. They were treated with either VNS + KD (with an interval < 5 days) or KD alone, in addition to standard therapy.
resultsEighteen children (nine females, nine males) with a median onset age of 8.1 years were studied. Before KD/VNS treatment, the average number of seizures (AS) per hour was 3.0 and the percentage of total duration of electrographic seizures (ESD) per hour was 65.5%. Median duration of anesthesia, duration of mechanical ventilation, and duration in ICU and hospital were 58.5, 39.5, 65.5, and 74.5 days, respectively. Four children received VNS + KD, and 14 received KD alone. The median time to intervention was 16.5 days after onset, and the median follow-up duration was 7.1 years. The VNS + KD group showed a significant reduction in average seizure frequency per hour (P = 0.002). However, no significant differences were observed in ESD or duration of status epilepticus (SE) (P > 0.05). And there were no significant differences between the groups in terms of duration of anesthesia, duration of mechanical ventilation, and duration in ICU and hospital (P > 0.05). At the last follow-up, 55.6% had moderate to severe disabilities, and 16.7% had died. The VNS + KD group exhibited significantly better functional outcomes as measured by the modified Rankin scale (P = 0.002). Younger age of onset was associated with increased odds of a poor outcome (P = 0.045).
conclusionFIRES patients experienced severe seizure burdens in the acute phase and had poor long-term prognoses. Combining VNS and KD treatments in the acute phase may represent a viable therapeutic strategy for reducing seizures and improving long-term function for pediatric FIRES.
