This figure summarizes the validations for (A) BDAE ‘cookie theft’ 15-word checklist, (B) BDAE ‘cookie theft’ 15-word checklist with cognitive measures of ACE-R and MLSE, (C) MLSE ‘beach scene’ 15-word checklist and (D) MLSE ‘beach scene’ 15-word checklist with cognitive measures of ACE-R and MLSE. The curved brackets under or next to the group names (e.g. Patients, ‘Motor’ and ‘Lexico-Semantic’) illustrate the number of participants who were classified correctly out of the total N. The percentages in red indicate the within-sample 4-fold and out-of-sample validation accuracies.
