  3. aThe odds ratio from multivariable logistic regression, adjusted for other variables in the table
  4. b only one individual was underweight and was observed to be non-hypertensive. The OR for this category is therefore, unreliable
  5. c Subgroup analysis in which controlled hypertension was defined as blood pressure ≤ 130/80 mmHg for individuals with diabetes mellitus
