significant correlation p values (in order: BNT, PPVT, NATNAVS, Rep66): p = 0.05, 0.022, 0.006, 0.021, (FDR corrected). Following partial correlation, covarying the effect of cortical atrophy, correlation between NAT-NAVS and IFG-MTG (r= 0.231, p=0.026) and Rep66 and IFG-MTG (r=0.246, p=0.019) remained significant.

BNT = Boston Naming Test; PPVT= Peabody Picture Vocabulary Test; NATNAVS = Northwestern Anagram Test-Northwestern Assessment of Verbs and Sentences; Rep66 = WAB repetition score. IFGt = Inferior Frontal Gyrus; MTG = Middle Temporal Gyrus; ATL = Anterior Temporal Lobe. PPA = Primary Progressive Aphasia.
