Spearman rank–order correlations between word fluency task performance for each clinical subgroup with aphasia, and the adjusted Western Aphasia Battery Aphasia Quotient (WAB AQ) and a 15-item Boston Naming Test (BNT).

Subgroup	WAB AQ				BNT
	svPPA	lvPPA	nfPPA/AOS		svPPA	lvPPA	nfPPA/AOS
Letter	0.68*	0.66*	0.24		0.42	0.48*	0.08
Category	0.84*	0.79*	0.58*		0.61*	0.68*	0.48*
Action	0.62*	0.69*	0.42*		0.31	0.44*	0.26

Note. svPPA = semantic variant primary progressive aphasia; lvPPA = logopenic variant primary progressive aphasia; nfPPA = nonfluent/agrammatic with or without apraxia of speech; AOS = apraxia of speech.
