Figure 2. Results of the 4-Group Analysis (Separating Patients With nfvPPA-CBD From nfvPPA-PSP).

Figure 2

All 5 speech timing measures captured significant impairments in patients with nfvPPA-CBD compared with both healthy controls and patients with svPPA. By contrast, only the articulation rate was impaired in the patients with nfvPPA-PSP. Deficits in all measures were significantly greater for patients with nfvPPA-CBD than nfvPPA-PSP. In the box plot, middle horizontal lines show each group's median, with lower and upper lines representing the 25th and 75th percentiles, respectively. The whiskers represent the smallest and largest values in the distribution. Colored dots indicate each participant's individual value. Black dots represent the group's mean. *Denote significant differences at p < 0.05. All statistics were calculated after outlier removal (namely, a single participant with nfvPPA-PSP). NfvPPA-CBD = nonfluent variant primary progressive aphasia with corticobasal degeneration pathology; nfvPPA-PSP = nonfluent variant primary progressive aphasia with progressive supranuclear palsy pathology; svPPA = semantic variant primary progressive aphasia.
