^*Daily dietary cost and dietary intake adjusted to a 2000 kcal/day diet using the residual method. Estimates shown are β coefficients from linear regression estimated based on 10 multiple imputations.

^†Model 1 is adjusted for age and sex; Model 2 is additionally adjusted for test site, education level, occupation, household income, marital status; Model 3 is additionally adjusted for BMI, objectively measured physical activity (energy expenditure) and smoking status. Adjusted means of dietary cost estimated based on model 3 and on single imputed dataset, after confirming no difference in beta coefficients between single and multiple (10) imputations.
