Fifteen variables (atrial fibrillation p = 0.000, systolic BP p = 0.024, diastolic BP p = 0.053, temperature p = 0.045, glucose p = 0.015, total cholesterol (TC) p = 0.004, prothrombin time (PT)% p = 0.002, international normalized ratio (INR) p = 0.009, fibrous protein (Fib) p = 0.003, cerebral infarction area (CIA) p = 0.000, cerebral infarction volume (CIV) p = 0.000, THRIVE score p = 0.000, NIHSS score p = 0.000, NIHSS score > 20 p = 0.000, thrombolysis p = 0.019) were statistically significant (Table 2). Here, F2 is linked to brain infarction.
