The blood urea nitrogen to creatinine (BUN/Cr) ratio is associated with early neurological deterioration in acute ischaemic stroke (AIS). However, the predictive value of the BUN/Cr ratio for the AIS prognosis remains unclear. Therefore, we evaluated the correlation between the BUN/Cr ratio and the 3-month outcome in patients with AIS, further testing their dose-response relationship.
