CST and Fminor FA values (mean and standard deviation) obtained with each of the tracking methods across the eight subjects for each of the three study waves.

Mean yearly change (last column) was defined as the average yearly change between two successive waves, i.e., $\frac{1}{2}\left[\frac{{\overline{FA}}_{wave2}-{\overline{FA}}_{wave1}}{3}+\frac{{\overline{FA}}_{wave3}-{\overline{FA}}_{wave2}}{3}\right]$.
