  1. The basic model included age, gender, current smoking, alcohol consumption, hospital, admission NIHSS score, SBP, DBP, high-density lipoprotein, medical history (hypertension, diabetes mellitus, atrial fibrillation), use of antihypertensive medications and lipid-lowering medications, time from onset to hospital, and stroke syndrome
  2. CI confidence interval, TyG index Triglyceride glucose index, IDI integrated discrimination improvement, NRI net reclassification index
