The early survival benefit of EVAR over open repair is consistently demonstrated, but this is reversed over time, with adjusted hazard ratios for total mortality beyond 8 years of 1.25, and a more than five-fold increase in aneurysm-related mortality. This late mortality is driven by a spectrum of graft-related eve…","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.
