↵a Data presented as mean (SD). χ² tests were used for categoric variables, and analysis of variance, for continuous variables. For clinical group comparisons, measures of WMH volumes and WMH annual change were log-transformed to normalize variance.
↵b Post hoc comparisons of significant group difference: CN vs MCI.
↵c Post hoc comparisons of significant group difference: CN vs AD.
↵d Post hoc comparisons of significant group difference: MCI vs AD.
