Supplementary file 1_Intraoperative 40 Hz gamma frequency auditory stimulation for postope

Supplementary file 1 is a study protocol authored by Xiaoxuan Hu and uploaded to figshare in April 2026. The document outlines the methodology for a randomized, double-blind controlled trial involving 342 patients undergoing laparoscopic gynecological surgery. It details the intervention, primary and secondary outcomes, and registration information for the clinical trial.

Use Cases

• Analyzing the relationship between auditory stimulation and postoperative sleep disturbance incidence based on the primary outcome measure.
• Modeling the effect of the intervention on secondary outcomes like anxiety scores (HADS-A) and quality of recovery (QoR-15).
• Studying correlations between sleep metrics and other recovery indicators such as pain scores and analgesic consumption.
• Designing meta-analyses or systematic reviews on non-pharmacological perioperative interventions based on the detailed methodology.

Strengths

• The protocol is for a randomized, double-blind controlled trial, a rigorous study design.
• The trial is registered with a public identifier (ChiCTR2500110341) on a clinical trial registry.
• The document specifies a sample size of 342 patients and a detailed list of primary and secondary outcomes.

Limitations

• The dataset is a 45.5 KB DOCX file containing a protocol, not the resulting clinical trial data.
• Column-level documentation for any eventual data is absent; field semantics must be inferred after download.
• Row count for the eventual trial results is unknown, which may limit suitability assessment.
