Patients with END were confirmed as the National Institutes of Health Stroke Scale (NIHSS) increased ≥ 4 points between hospital days 0 and 5. Multivariate logistic regression analysis was used to analyze the factors independently related to END in patients with AIS.Results: In total, 202 patients diagnosed with AIS were enrolled in this retrospective study. Using ROC curve analysis, patients were divided into two groups according to LMR: low LMR group (LMR < 3.24, n = 95) and high LMR group (LMR ≥ 3.24, n = 107). The frequencies of END were significantly higher in the low LMR group compared to the high LMR group (41.05 vs.15.89%, p < 0.001). Multivariate logistic regression showed that age (OR = 1.03, 95% CI 1.01– 1.06, p = 0.04), infarct volume (OR = 1.01, 95% CI 1.00– 1.02, p = 0.001), neutrophil count (OR = 1.17, 95% CI 1.03– 1.33, p = 0.018), and LMR (OR = 2.49, 95% CI 1.01– 9.11, p = 0.018) were independently associated with END in AIS patients.Conclusion: A peripheral LMR levels at admission were significantly associated with END and LMR < 3.24 is an independent predictive factor of END in patients with AIS.Keywords: lymphocyte-to-monocyte ratio, acute ischemic stroke, early neurological deterioration, national institutes of health stroke scale
