HCMV human cytomegalovirus, HCMV− human cytomegalovirus seronegative, HCMV+ human cytomegalovirus seropositive, ROI region of interest, FWE family-wise error rate, R.IFOF right inferior fronto-occipital fasciculus, L.IFOF left inferior fronto-occipital fasciculus, MNI Montreal Neurological Institute.
aBi-sided cluster peak t-value is shown; A negative value indicates that HCMV+ participants have lower FA than HCMV− participants.
bClustering method was faces or edges touch.
cCluster peak MNI coordinates are shown. The X, Y, Z dimensions refer to left (+) to right (−), posterior (+) to anterior (−), and inferior (+) to superior (−).
