highly significantP < 0.001
Gene pairs showing highly significant ( P < 0.001) correlations between their expression levels in PTG-stimulated biopsies from controls (but not in the GFD group) were selected as the control-specific coexpression signature, whereas gene pairs showing highly significant correlations after PTG challenge of GFD celiac biopsies (but not in the case of controls) formed the GFD-specific coexpression signature.
