However, its role in acute ischemic stroke (AIS) remains still unknown. Therefore, this prospective study aimed to investigate the association between admission serum glucose-phosphate ratio and the severity and 1-year clinical outcome of AIS.Methods: All the patients with AIS were enrolled from the Third China National Stroke Registry III. Participants were classified into four groups according to quartiles of admission serum glucose-phosphate ratio levels. Multiple regression models and restricted cubic splines were performed to evaluate the association between serum glucose-phosphate ratio and the severity and 1-year outcome of patients with AIS.Results: Among the 5,541 participants, the mean age was 62.3 years, and 69.4% patients were men. As the quartiles of admission serum glucose-phosphate ratio increased, the median NIHSS score raised, the percentage of moderate and severe stroke elevated, and rates of poor functional outcomes and recurrent stroke raised at one-year follow-up. After adjusting conventional risk factors, the highest admission serum glucose-phosphate ratio-level quartile group showed an association of poor functional outcome and stroke recurrence [OR (95% CI): 1.67 (1.28, 2.17) and HR (95% CI): 1.44 (1.08, 1.92), respectively], relative to the lowest group. Restricted cubic splines showed no significant nonlinear relationship between serum glucose-phosphate ratio and adverse outcomes of AIS.Conclusion: Admission serum glucose-phosphate ratio may be a potential blood biomarker for reflecting stroke severity, predicting poor functional outcomes, and stroke recurrence.Keywords: serum glucose-phosphate ratio, acute ischemic stroke, outcome, severity, blood biomarker |
