Inter-network functional connectivity (FC) among five functional networks during the gratitude and resentment interventions (A) and after the interventions (B). Average inter-network FC values across subjects before, during, and after the interventions are shown in insets (A and B). Paired sample t-tests were conducted to compare inter-network FC during the two interventions. Meanwhile, repeated-measures analysis of variance (RM-ANOVA) tests were performed to compare inter-network FC before and after the interventions. The detailed descriptions for the mean, standard deviation, and statistical value are summarized in Supplementary Tables S9 and S10. As shown in the last column in insets (A and B) statistical significances were presented in the form of −log10 (P _FDR), where P _FDR is the corrected p-value for multiple comparisons using false discovery rate (FDR). Furthermore, post-hoc analysis was carried out for significant inter-network FCs in the RM-ANOVA test (C). Standard errors on a bar graph were plotted in an inset (C). Abbreviations: G > R (G < R) indicates that inter-network FC during the gratitude is higher (lower) than that of during the resentment; rsFC, resting-state FC.
