IDI: integrated discrimination index; NRI: Net Reclassification Index; SBP: systolic blood pressure; SE: standard error.
aModel 1: Age, gender, NIHSS, eGFR, stroke subtype, history of hypertension, diabetes, smoking, dyslipidaemia, coronary artery diseases, TIAs, atrial fibrillation and in-hospital treatment (aspirin, anticoagulation, thrombolysis).
