Even though groups were sex-matched, we recomputed the correlation on the loading components to ensure that no sex-differences existed. In women only, the correlation between the EEG-coherence and NAcc seed-correlation components was r = − 0.56 (uncorrected p = 0.037), and in men only the correlation was r = − 0.60 (uncorrected p = 0.001). Due to the smaller sample sizes, the correlations no longer reached corrected significance, but we found no evidence for sex-differences in the relationship between the fMRI network and EEG coherence networks estimated.
