Figure 5. Example of group-difference statistics.

Figure 5

Each point on the medial representation of CC is colored with the weighted average FA over all corresponding points on the clustered trajectories for (a) young and (b) elderly group. The results clearly show the spatial variation of FA along the cluster and lower FA in the elderly population. The corresponding p-value for the group difference in FA is shown in (c) for CC and (d) right CST. Red corresponds to regions with high statistical significance (p ≤ 0.001).
