Data are presented as median (interquartile range) for continuous variables and n (%) for categorical variables. p < 0.05 was considered statistically significant. AIS, acute ischemic stroke; GNRI, Geriatric Nutritional Risk Index; ALT, alanine aminotransferase; UA, uric acid; TG, triglyceride; NLR, neutrophil-to-lymphocyte ratio; MLR, monocyte-to-lymphocyte ratio; PLR, platelet-to-lymphocyte ratio; SBP, systolic blood pressure; DBP, diastolic blood pressure.
