Sliding window correlation was used to calculate the variability of the dFCD. The changes in dFCD\u2010based dEC between the two groups were examined using Granger causal analysis. To describe the time\u2010varying Granger causality, a sliding\u2010window approach was utilized to divide time courses into a group of windows.

In state 1, OAB patients had excitatory effective connections from bilateral ACC to left mPFC in comparison to HC. In state 2, there was an increase in dEC from the SMA to the mPFC. Participants with OAB showed significantly more inhibitory dorsolateral prefrontal cortex (dlPFC) connections between the left ACC and the right ACC in state 4, as well as an excitatory dEC connection
