Specifically, 12-month primary patency ranges from approximately 62.2% to 89% for AVFs compared to 46.0% to 56% for AVGs, while infection rates are nearly dou…","trust_label":"machine_generated_human_reviewed","editorial_verification":{"status":"human_reviewed","trust_label":"machine_generated_human_reviewed","method":"World ID proof-of-human editorial account","scope":["clinical_integrity","reference_quality","scientific_coherence"],"verification_note":"This Evidence Object is machine-generated and human-reviewed.
