Figure 1 Mean performance on pre-treatment, post-treatment, and follow-up measures for all LRT participants.

Note: 95% confidence intervals around the mean were derived using n=1000 bootstrapped samples.
Abbreviations: LRT, lexical retrieval treatment; BNT, Boston Naming Test; WAB AQ, Western Aphasia Battery Aphasia Quotient.

Figure 2 Mean pre- to post-treatment change scores (post minus pre) for participants completing LRT in person or via teletherapy.

Table 4 Mean performance on trained and untrained items (SDs) for LRT participants by treatment type

Notes: Positive values indicate higher scores at post-treatment than pre-treatment. Error bars are not presented as significance was derived via permutation tests. The 95% CIs obtained via permutation are presented in the text.
