Values denote means ± SD (range). ‘Time’ is reported in terms of seconds. The following items were randomly selected from the original test: 1–2–6–8–9–10–11–12–13–14–15–19–20–23–24–30–31–32–33–34–37–41. p values refer to Mann–Whitney U test and were adjusted for multiple comparisons controlling the False Discovery Rate at level .05, using Benjamini-Hochberg step-up procedure.
Abbreviations: lvPPA = logopenic variant of primary progressive aphasia; nfvPPA = nonfluent variant of primary progressive aphasia; svPPA = sematic variant of primary progressive aphasia; NAT-I = Northwestern Anagram Test-Italian.
