Effect of transcutaneous auricular vagus nerve stimulation on perioperative anxiety in patients undergoing radical mastectomy: study protocol for a randomized controlled clinical trial.
Article in Frontiers in neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Background: Breast cancer patients often experience significant concerns regarding surgery, which predisposes them to negative emotions such as anxiety, adversely affecting both surgical outcomes and postoperative recovery. However, research on interventions for perioperative anxiety remains limited. This study focuses on patients undergoing radical mastectomy to investigate the effects of transcutaneous auricular vagus nerve stimulation (taVNS) on perioperative anxiety, aiming to provide novel clinical strategies for its prevention and management. Methods: This prospective, double-blind, randomized controlled trial will enroll 202 eligible patients with radical mastectomy. Patients are randomly assigned to either the treatment group (taVNS group) or the control group (sham stimulation group). In treatment group, taVNS is administered 30 min before anesthesia induction and at the same time point daily for postoperative days 1-3, using specific stimulation parameters. The control group was given a sham stimulus. Primary outcome is the perioperative anxiety remission rate, which assessed by comparing post-intervention (after the final session) and pre-intervention (before the first session) scores in patients subjected to either full-course taVNS or sham stimulation. Secondary outcomes are Hamilton Anxiety Rating Scale (HAMA), Pittsburgh Sleep Quality Index (PSQI), 3-Minute Diagnostic Interview for Confusion Assessment Method-Defined Delirium (CAM-3D), Numerical Rating Scale (NRS), Fatigue, Resistance, Ambulation, Illnesses, and Loss of Weight (FRAIL) and heart rate variability (HRV). Discussion: The strength of this study lies in the adoption of taVNS as an intervention for perioperative anxiety and the establishment of a comprehensive efficacy evaluation system. taVNS may alleviate anxiety by modulating autonomic nervous function and restoring the balance between sympathetic and parasympathetic activity. This study aims to provide an innovative approach for mitigating perioperative anxiety, with the potential to improve patient outcomes and enhance quality of life.
