Note. sv = semantic variant; lv = logopenic variant; LRT2 = Lexical Retrieval Training Protocol 2; LRT1 = Lexical Retrieval Training Protocol 1; Trained = percent correct for trained items; Untrained = percent correct for untrained items; BNT = percent correct on Boston Naming Test (Full BNT was administered at pre- and post-treatment and equivalent short [15-item or 30-item] versions were administered at follow-up testing sessions. Only equivalent subsets of items were used for statistical comparisons across time points and groups.); WAB = Western Aphasia Battery (AQ out of 100); MMSE = Mini-Mental State Examination (out of 30); TT = received treatment via teletherapy; N/C = not collected.
