Jonckheere tests specified these results by the determination of highly significant trends between categories of self-ratings and the linked clinical measures ( p ≤ 0.001 to 0.005) indicating that objective measures differed according to categories of self-ratings (see Table 5 ).
Trend tests identified a significant trend between values of the clinical assessment and categories of self-ratings ( p ≤ 0.01) with lower cognitive status derogating this relationship.
However, for “lower extremity muscle strength” and self-care “eating and drinking” and “personal hygiene” associations and trends in patients with lower MMSE scores did not reach statistical significance suggesting partly reduced insight of patients with lower cognitive status (see Table 6 ).
