Fig. 5.

The moderation analysis for EPT arousal ratings. The moderating effect of group (meditation vs. relaxation) is depicted on the association of changes in the rs-FC between the PCC/precuneus and the predefined PRN mask, and in participants' arousal ratings on the (a) positive- and (b) negative-valenced pictures following training. The models additionally controlled for the effects of the pre-training PCC/precuneus-PRN rs-FC, training-related changes in valence ratings of positive (a) and negative (b) pictures, as well as age, sex and years of education. Both unstandardized regression coefficients and the associated standard errors are shown for the main effect and the moderating effect. * indicates effects that are significant at p < 0.05. Red and blue arrows denote positive and negative effects, respectively. Please note that the direction of an arrow denotes the hypothetical rather than established direction of an effect. Med: Meditation group, PCC: posterior cingulate cortex, Rel: Relaxation group, Rs-FC: resting-state functional connectivity, SE: standard error, Unstd coef: unstandardized coefficients.
