Results from the whole brain contrast analyses and covariate analyses using the general linear model to test for group differences in intrinsic connectivity are presented here.We only report group differences significant at p<.05, corrected for family wise error using SPM8. We also report results for the analysis after controlling for depression and anxiety. Missing probability values for covariate analysis indicate the cluster did not achieved an uncorrected p value <.05 uncorrected. All regions are represented in Montreal Neurological Institute (MNI) space with X, Y, Z coordinates.
Abbreviations: BA, Brodmann's area; HC, healthy control; IBS, irritable bowel syndrome; k, number of voxels in the cluster; LPVD, localized provoked vulvodynia; PMC, primary motor cortex; p, probability value corrected for family wise error rate; PSC, primary somatosensory cortex; SMA, supplementary motor area; STC, superior temporal cortex
