Valid clinical information was defined as categories 1 and 2. Data on patients from the general population were obtained from Phung et al. [17]. Level of significance between patient groups based on the Kruskal-Wallis tests.
a
Post hoc comparisons using the Tukey HSD test indicated that the mean score differed significantly from elderly patients.
b
Post hoc comparisons using the Tukey HSD test indicated that the mean score differed significantly from young patients, dementia confirmed.
c
Level of significance was based on ANOVA.
