Data is represented as mean ± SD unless otherwise indicated.
SIVD = Subcortical ischemic vascular disease. AD = Alzheimer's disease. NC = normal cognition.
§The Analysis of Variance (ANOVA) and Chi-square test are used wherever appropriate. Significant between-group differences are remarked as aSIVD vs. AD; bSIVD vs. NC; cAD vs. NC. Median of white matter hyperintensities (SIVD/AD/NC/overall) = (37.4/10.2/2.2/14.2) ml. Median of the lacune number (SIVD/AD/NC/overall) = (17/7/4/8).
