meta project 1

This repository contains the raw data used in the systematic review and meta-analysis comparing different arteriovenous fistula cannulation techniques (rope-ladder, area, and buttonhole) in patients undergoing maintenance hemodialysis. The dataset includes extracted study-level information from all eligible randomized controlled trials, including study characteristics, sample sizes, intervention and comparator groups, and outcome data related to short-term complications (infection and bleeding), long-term complications (aneurysm formation, stenosis, and occlusion), and cannulation success rates. All data were independently extracted by two reviewers according to predefined inclusion criteria and were used solely for quantitative synthesis. No individual patient-level data are included. The dataset is provided to enhance transparency, reproducibility, and secondary analyses.
