Figure 2.
Visualization scheme: (a) The strongest transition among the three instantaneous links from each state are shown in blue while other transitions are drawn in dotted black. The line width and the node size reflect the expected count. The node color represents the average sojourn time (red to green: 0 to 5 years and above). (b) similar to (a) but the strongest transition from each state is color coded as follows: Aβ direction (blue), hippo (green), cog (red), Aβ + hippo (cyan), Aβ + cog (magenta), hippo+cog (yellow), Aβ + hippo + cog(black). The node color represents the average sojourn time (red to green: 0 to 3 years and above).
