Data Analysis of Pre-operative Anxiety with RoB

This dataset supports the article “Factors Associated with Preoperative Anxiety in Cardiac Catheterization Patients: A Meta-Analysis.” The dataset contains extracted and analyzed data used in a meta-analysis assessing factors influencing preoperative anxiety among patients undergoing cardiac catheterization. A total of 14 cross-sectional studies (2015–2025) were included. Data were processed and analyzed using Review Manager (RevMan) version 5.3, including effect sizes, confidence intervals, and heterogeneity statistics for each factor. Variables analyzed include gender, social support, history of surgery, and education level. Key findings: Female gender, high social support, and prior surgical history reduce anxiety, whereas higher education level increases anxiety.
