Transradial versus Transfemoral Access and the Risk of Acute Kidney Injury following Primary Percutaneous Coronary Intervention in Patients with ST-Elevation Myocardial Infarction: A Systematic Review and Meta-Analysis of Randomized Controlled Trials and Propensity-Score-Matched Studies

Forest plot. Forest plot using random effects model that demonstrates that transradial access is nonassociated with a significantly lower risk of contrast-induced acute kidney injury in patients undergoing primary percutaneous coronary intervention for ST-elevation myocardial infarction compared with transfemoral access even after dividing the studies by research type (group 1: randomized controlled trials, group 2: studies where propensity score matching was used).
