The lymphocyte-to-monocyte ratio (LMR) is a novel inflammatory marker that has been shown to be associated with various diseases. However, the relationship between the LMR and SAP in patients with AIS remains unclear.<h4>Methods</h4>A retrospective cohort study was conducted on 1,063 patients with AIS admitted to our hospital within 72 hours of symptom onset. Patients were divided into two groups: the SAP group (<i>n</i> = 99) and the non-SAP group (<i>n</i> = 964). The LMR was measured within 24 hours of admission, and the primary outcome was the incidence of SAP.
