Fig. 3. Group differences of occurrences and dFNC patterns in cLBP patients and HCs.

Fig. 3

a In Dataset 1, cLBP patients (pre- and post-maneuver) had significantly lower fraction rate and dwell time in State 1 and higher fraction rate and dwell time in State 2. This finding was validated in Dataset 2. Data are presented as mean values ± SEM. Each circle represents the data for an individual. N = 90 and 74 for cLBP patients and HCs in Dataset 1, respectively, and N = 30 and 30 for cLBP patients and HCs in Dataset 2, respectively. b The fraction rate and dwell time of cLBP patients in State 2 were positively correlated with pain severity/intensity in the past 7 days. Note that pain severity and intensity are two different measures but are typically strongly correlated. c cLBP patients and HCs had similar patterns of connectivity in the two states, but they differed in the strength of connections. Asterisks represent significant difference at two-sided pFDR < 0.05 for t-test.
