2.8.3. Temporal Properties and Connectivity Strength of Dynamics States
DISEASE
Three parameters were measured to assess the temporal properties of FNC: (1) fraction time (the frequency of each state); (2) mean dwell time (the average time a subject spent in any state without converting to another state); (3) number of transitions (switching times between different states). Besides, the connectivity strength of 3 states within the TATG group and the SATG group was also calculated. Analysis of covariance (ANCOVA) was used to compare the mean changes from before treatment to after treatment between groups. Disease duration and lesion volume were taken as covariates. And paired samples
