SAI, stroke associated infection; NIHSS, National Institute of Health Stroke Scale; NPAR, neutrophil percentage-to-albumin ratio; OR, odds ratio; CI, confidence interval. Model 1: adjusted for age, male, smoke, initial NIHSS, atrial fibrillation, and NPAR. Model 2: adjusted for age, smoke, initial NIHSS, atrial fibrillation, and NPAR.
