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
objectiveVagus nerve stimulation (VNS) is an established adjunctive therapy for pediatric drug-resistant epilepsy (DRE), but objective evidence of its early impact on overall health is limited. Subjective seizure diaries can be influenced by placebo effects, whereas healthcare utilization may serve as a more objective window into the early post-operative course. This study aims to evaluate healthcare utilization in the immediate and subacute recovery phase (0-3 months) following VNS implantation in a large cohort of children with DRE.
methodsWe performed a retrospective, single-center, single-surgeon study of 200 consecutive patients (< 20 years old) with DRE who underwent first-time VNS implantation at a Level IV pediatric epilepsy center. The primary outcome was change in acute healthcare utilization, assessed by comparing rates of all-cause and seizure-related unplanned hospital admissions and emergency room (ER) visits in the 90 days before and after surgery.
resultsUnplanned acute healthcare utilization significantly decreased in the 90-day post-operative window compared to preoperative baseline. All-cause unplanned hospital admissions decreased significantly (p = 0.045). This change was driven by a marked reduction in unplanned seizure-related admissions. Unplanned seizure-related admissions decreased from 34 events to 14 (58.8% reduction), and seizure-related ER visits fell from 60 to 35 (41.7% reduction). The acute surgical safety profile was excellent. Ambulatory concerns expressed by patients and caregivers (electronic, telephone, or in clinic encounters) were rare but most commonly involved pain, hoarseness, cough, and wound care questions.
conclusionsIn a large, consecutive, single-surgeon series, pediatric VNS implantation was associated with an early reduction in unplanned acute healthcare utilization and an exceptional surgical safety profile. Our observations suggest that VNS provides a rapid and clinically significant reduction in unplanned seizure-related hospital admissions and ER visits within the first 3 months of implantation. This suggests an early benefit of VNS for children with DRE.
