Analyzed using Cox proportional hazards regression models. Adjusted by age, sex, marital status, education level, income level, multimorbidity, smoking, alcohol, BMI, ADL, IADL, and MMSE. Age, BMI, ADL, and IADL are continuous variables.
HR, hazard ratio; CI, confidential interval; BMI, body mass index; ADL, activities of daily living; IADL, instrumental activities of daily living; MMSE, Mini-Mental State Examination.
