Infratentorial structural covariance networks of non-demented subjects. For areas included in each of these networks, refer to Table 2. Box–whisker plots indicate grey-matter integrity per decade, and p value indicates significance of age as predictor of network disintegration (adjusted for sex, and education, and corrected for multiple comparisons; FDR, q = 0.05, significant networks are marked with an asterisk). Networks u–x show a reduction of grey-matter network integrity with increasing age. The number of subjects within the age ranges is indicated in parenthesis
