Comparative efficacy and safety of mid-neck vs. supraclavicular vagus nerve stimulation in pediatric drug-resistant epilepsy.

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
objectivesA supraclavicular insertion approach for vagus nerve stimulation (VNS) may permit a wider range of VNS settings compared to traditional insertion techniques due to increased anatomic distance between VNS leads and the recurrent laryngeal nerve. Beyond potential technical advantages, this approach could offer greater cosmetic satisfaction for patients. However, the safety and efficacy of the supraclavicular approach is uncertain. We compared safety and efficacy of supraclavicular versus mid-neck insertion techniques for VNS in the treatment of pediatric drug-resistant epilepsy (DRE).
methodsSingle-center retrospective analysis of children with epilepsy (< 21 years of age) who received VNS via supraclavicular or mid-neck insertion from May 2017 to December 2022. Continuous variables were compared using Wilcoxon rank-sum tests, while categorical variables were analyzed with Fisher's exact tests.
resultsThe study included a total of 88 patients (Male/Female:38/50), with 18 having supraclavicular and 70 mid-neck VNS insertions. No significant differences between groups were found in demographics, clinical/seizure characteristics, VNS settings, side-effect profile related to VNS surgery or stimulation, or seizure outcomes at last follow up.
conclusionsThe supraclavicular approach to VNS does not differ from the mid-neck method in terms of efficacy and overall safety profile. Future research with a larger cohort and longer-term follow-up is needed to explore the clinical significance of VNS settings in the context of different lead locations.
