  1. a: Prevalence Odds Ratio: They indicate what is the chance of having dependency in the BADL in each group compared to the reference group (first group) of each risk factor?
  2. b: In the bivariate analysis
  3. c: Adjusted OR (95%CI) have been displayed only for the risk factors that remained in the final multiple logistic model, after fitting the model by the backward method. The risk factors “age”, “sex”, “education”, “diabetes mellitus”, “hypertension”, “low HDL cholesterol”, “high serum triglyceride”, “high waist circumference” “physical activity” and “daily intake of calories” entered into the first multiple logistic model and after fitting the model by the backward method, the covariates “age”, “sex”, “education”, “low HDL cholesterol”, “physical activity” and “daily intake of calories” remained in the final model
  4. d: In the multiple logistic regression
  5. e: Mean (Standard Deviation)
