Nonlinear Relationship Between Blood Urea Nitrogen to Albumin Ratio and 3-Month Outcomes in Patients With Acute Ischemic Stroke: A Second Analysis Based on a Prospective Cohort Study

Patients with acute ischemic stroke (AIS) have limited evidence regarding the relationship between blood urea nitrogen and albumin (BUN/ALB). Aiming to investigate the relationship between the BUN/ALB ratio and poor outcomes in AIS patients at 3-months was the purpose of this study.
