Single factor analysis showed a statistically significant difference in ischemic stroke (p = 0.000), CAHD (p = 0.007), vascular stenosis (p = 0.000), hypertension (p = 0.000), age (p = 0.000), DBIL (p = 0.035), AST (p = 0.012), FIB (p = 0.009), FT3 (p = 0.000), FT4 (p = 0.000), CEA (p = 0.000), CA199 (p = 0.004), SBP (p = 0.000) in the LA versus no LA population; while the difference in gender, epilepsy, diabetes, hyperlipidemia, smoking, alcohol consumption, BMI, TC, TBIL, IBIL, ALT, TG, LDL, HDL, HbA1c, FBG, UA, DBP was not statistically significant (Table 1). Here, GPT is linked to ischemic stroke.
