Global measures of the WM structural network were quantified in the aMCI converters, non-converters, and controls. The bars and error bars represent the fitted values and the standard deviations, respectively. The fitted values indicates the residuals of the original values of the network metrics after removing the effects of age, gender and years of education. The asterisk indicated a significant difference between groups. (*) represents a significant group difference at p < 0.05; (**) represents a significant group difference at p < 0.01; and (***) represents a significant group difference at p < 0.001.
