aModel included age, sex, marital status, education, medical consultation, current/past history of major disease, and smoking.
bDue to missing data, only 1125 subjects for dependence in ADL and 1227 for death or composite outcome were included in the analyses.
cParticipants who died during follow-up were excluded from this analysis.
