Similar to frequency results, phase differences between the DMN and frontoparietal network were also significantly positively correlated to pain duration in CBP (R = 0.68, p<0.05), showed a positive trend in OA (R = 0.64, p = 0.053), and was not significant in CRPS (R = 0.19, p = 0.79) ( Figure 5B ).
