Analysis of the Outcomes Studied in the Application of Invasive and Non-Invasive Vagus Nerve Stimulation in Clinical and Preclinical Studies Involving Stroke-A Scoping Review.
Review in NeuroSci, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCurrently, there is a considerable number of studies addressing vagus nerve stimulation (VNS) for the treatment of different stroke-related outcomes. We aimed to promote a broad view of the outcomes studied and what are the opportune outcomes to be studied involving this therapeutic strategy for the treatment of post-stroke complications.
methodsThis is a scoping review that followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Two investigators conducted independent searches on PubMed/MEDLINE, Scopus, and Embase till July 2025. Randomized clinical trials and preclinical studies using invasive or non-invasive vagus nerve stimulation conducted with a population diagnosed with stroke were included.
resultsForty-one experimental studies and sixteen clinical trials were included. The outcomes found were neuroprotection; motor, functional, and cognitive rehabilitation; dysphagia; comparison of different stimulation intensities; safety, efficacy, and feasibility of the non-invasive approach; comparison between transcutaneous auricular vagus nerve stimulation (taVNS) and transcutaneous cervical vagus nerve stimulation (tcVNS); and comparison between two models of ischemia (permanent and transient). Preclinical studies mostly investigated molecular elements involved in neuroprotection, neuroinflammation, and cellular apoptosis, while clinical studies evaluating the effectiveness of this technique used for rehabilitation and its comparison or combination with other techniques remain scarce.
conclusionsMost studies investigating the effects of VNS on different post-stroke outcomes are experimental studies. Clinical studies are still scarce and with limited analysis of outcomes.
