Among the four groups, there were significant differences in age (p < 0.001), sex (p = 0.005), smoking (p = 0.004), NIHSS (p < 0.001), TG (p = 0.005), FBG (p = 0.005), HCY (p = 0.041), Cr (p = 0.002), CHD (p = 0.012), HGB (p = 0.001), and β-blocker drugs (p < 0.001) among the four groups. Here, CYGB is linked to coronary artery disorder.
