Fig. 2From: The modulation effect of longitudinal acupuncture on resting state functional connectivity in knee osteoarthritis patients a Shown in green: after treatment, the increase in functional connectivity between the rFPN and left insula/putamen positively correlated with the change in KOOS pain score. Shown in red: the verum group showed significant increase in connectivity between the rFPN and left insula/putamen compared to sham group. (X = −30) b Results in a after adjusting for age and duration of pain. The comparison between verum and sham shown in red were at a less conservative threshold of voxel-wise Z > 1.96 and a corrected cluster significance threshold of P < 0.05Back to article page
