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
purposeEpilepsy following non-accidental trauma (NAT) occurs in 18% of pediatric patients. About 33% of patients with epilepsy develop drug-resistant epilepsy. For these patients, vagus nerve stimulation (VNS) is a palliative treatment option. We aimed to investigate the effectiveness of VNS among pediatric NAT-related epilepsy patients compared to those with non-NAT-related epilepsy.
methodsWe performed an 11-year retrospective analysis of VNS implantations for drug-resistant epilepsy at UPMC Children's Hospital of Pittsburgh. Patients were split into two groups: NAT vs. non-NAT. The primary outcome was the attainment of ≥ 50% seizure frequency reduction at 1-year post-VNS implantation. Fisher's exact tests and Wilcoxon rank-sum tests were used to compare groups. Significance was assessed at the alpha = 0.05 level.
resultsThis analysis included data from 370 pediatric VNS patients, of whom 9 had NAT-related epilepsy. NAT patients had a significantly younger age of epilepsy onset than non-NAT patients (0.3 years vs. 3.3 years). Otherwise, there were no statistically significant baseline differences between groups, including patient sex and quantity of antiseizure medications pre-VNS. Overall, 71% of NAT patients experienced ≥ 50% seizure frequency reduction compared to 48% of non-NAT patients (p = 0.269).
conclusionVNS may allow a higher proportion of pediatric patients with NAT-related epilepsy to achieve ≥ 50% seizure frequency reduction compared to other epilepsy etiologies. While the results of this study were not statistically significant, the effect size was large. Our results underscore the need for larger, multi-center studies to validate the effectiveness of VNS for this patient population.
