EPVS: enlarged perivascular spaces; DWMHs: deep white matter hyperintensities; PVWMHs: periventricular white matter hyperintensities; CMBs: cerebral microbleeds; AIS: acute ischemic stroke; IQR: interquartile range; SD: standard deviation. Data were analyzed by the t-test, Mann-Whitney U-test, Kruskal-Wallis test, or chi-square test.
