significantly decreased versus controls after FDR correction for multiple comparisons (p < 0.05). p values (top to bottom): p = 0.001, 0.002, 0.002, 0.001, <0.0005. ANCOVA analyses showed that the IFG-MTG connection in PPA-G continued to be significantly decreased when cortical volume was included as a covariate (p=0.036). In PPA-L patients there was only a trend towards significance (p=0.082).
