Adjusted hazard ratios (95% CI) of SAP outcome by linear splines of (A) PNI, (B) CONUT, and (C) GNRI with three same spacing knots. The solid line indicates the point estimate, and the shaded area is the 95% CI. Models were adjusted by age, sex, drinking, and smoking, body mass index (BMI), dysphagia, white blood cell count (WBC), and serum creatinine, diabetes, atrial fibrillation, hypertension, coronary heart disease, hyperlipidemia and NIHSS. Abbreviation: CONUT, controlling nutritional status score; GNRI, geriatric nutritional risk index; PNI, prognostic nutritional index; SAP, stroke-associated pneumonia
