Significantly different and highly significantly different mean values are marked by * and **, respectively. Susceptibility values are stated as mean ± 95% confidence interval (Pearson correlation coefficient r with age, p-value of r); p is the p-value of the group differences; d is the effect size. T: Values referenced to bilateral mean of thalamus. C: Values referenced to bilateral mean of caudate nucleus.
