We would like to have these issues corrected to our recent publication [].
Text Correction
In Section 2.1: The published sentence “These participants were classified into one of three PPA variants (3 nfvPPA, 5 svPPA, and 5 lvPPA), or as mxPPA (5 subjects) presentations” should be replaced with “These participants were classified into one of three PPA variants (3 nfvPPA, 5 svPPA, and 5 lvPPA), or as mxPPA (5 subjects) presentations”. We reanalyzed the data of a patient diagnosed with nfvPPA submitted to the sentence production program in a preliminary application of the program [].
In Section 4.2: The published sentence “C15 received prophylaxis treatment and presented no significant change in the trained items (but there was an increase in the correctness of the trained items)” should be replaced with “C15 received prophylaxis treatment and presented a significant change in the trained items (there was an increase in the number of correct responses in the trained items)”.
Error in Tables
Intervention focusing on sentence production: C15 and C16. The information reported in this table referred to the number of correct verbs (n = 20) instead of the number of correct sentences (n = 40). The correct information for these lines of the Table 3 (results of the intervention) are:
