Mean of semantic variant primary progressive aphasia (svPPA) patient and control participant demographic and clinical information.

Group	Control	svPPA
N (female)	19 (12)	13 (7)
Age (SE, Range)	65.2 (1.71, 53–78)	61.8 (2.06, 49–71)
Education (SE, Range)	15.6 (0.60, 12–20)	16.5 (0.75, 12–22)
Duration from symptom onset (SE, Range)	--	3.69 (0.12, 1–9)
MMSE (SE, Range)*	29.6 (0.16, 28–30)	22.7 (1.72, 14–30)
BNT Mean Z-score (N<−1.96, Range)	--	−14.7 (13, −16.1– −9.07)
Animals Mean Z-score (N<−1.96, Range)	--	−2.25 (11, −3.23– −0.80)
Digit Span Forward Z-score (N<−1.96, Range)	--	−0.54 (1, −3.14–0.83)
Digit Span Reverse Z-score (N<−1.96, Range)	--	−1.22 (2, −3.73–0.35)

Significant differences between controls and patients with svPPA indicated by * (p=0.002 using independent samples t-test). Patient z-scores for cognitive measures relative to healthy control data (z-score < −1.96 equivalent to p<0.05).

Abbreviations: N=number; SE=standard error; svPPA=semantic variant primary progressive aphasia; MMSE=mini-mental state examination; BNT=Boston naming test; N<−1.96=number of patients scoring significantly worse than controls (p<0.05)
