Table C2.

Results of paired permutation tests comparing outcome measures and standardized tests at each time point relative to pre-treatment and post-treatment for logopenic primary progressive aphasia.

Note. One-tailed tests were used for trained items for all comparisons to pre-treatment performance. All other comparisons utilized two-tailed tests. Trained = trained items; Untrained = untrained items; BNT = Boston Naming Test; WAB = Western Aphasia Battery.

^* Bonferroni-corrected thresholds for significance: p < 0.013 for comparisons to pre-treatment performance and p < 0.017 for comparisons to post-treatment performance.
