- NIHSS, National Institutes of Health Stroke Scale
- The logistic regression analysis results revealed that elderly age (≥75 years old), male gender, atrial fibrillation, dysphagia, an NIHSS score of 5–15 points, NIHSS of ≥16 points, and fasting hyperglycemia were independent risk factors of SAP (P < 0.05)
