Preoperative high-sensitivity C-reactive protein-to-albumin ratio predicts arteriovenous fistula failure in hemodialysis patients: a retrospective cohort study with landmark analysis
Background The arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis, yet up to 50% of AVFs fail within the first year due to stenosis or thrombosis. The high-sensitivity C-reactive protein to albumin ratio (HRR) integrates inflammation and nutritional status, but its association with AVF failur...
