Dementia risk for hemodialysis duration. The dementia risk for hemodialysis duration was analyzed for each different patient group using the age-adjusted or multifactor model. The age-adjusted model included only age and hemodialysis duration as independent variables. The multifactor model included baseline factors from the age-adjusted model plus additional clinical covariates (i.e., sex, comorbidity of diabetes, Kt/V, BMI, albumin level, CRP level, hemoglobin level, history of myocardial infarction, limb amputation, or hip fracture, ADLs, and place of residence). The duration of hemodialysis was treated as a continuous variable. Please note that the X axis is a linear plot. a The target patients of the analysis were the whole target patients. b The target patients of the analysis were only the non-diabetic patients. c The target patients of the analysis were only the diabetic patients. Asterisk indicates the number of patients who suffered dementia. Dagger indicates ORs for development of dementia for every 10 years of hemodialysis duration.
