↵*P values are based on one-way analysis of variance for continues variables and X² test for categoical variable.
† Mean FI = mean number of health deficits reported/total health deficits measured in instrument; score between 0 and 1 where higher scores represent worse health.
‡ Scores ≥ 0.25 indicate frailty. Missing N (%) for variables: morbidities=542 (2%); ADL=43 (<1%); IADL=76 (<1%); psychosocial health=465 (2%); HRQoL=534 (2%); self-rated health=72 (<1%).
ADL, activities of daily living; FI, Frailty Index; HRQoL, health-related quality of life; IADL, instrumental activities of daily living.
