  1. Abbreviations:μg micrograms; mg milligrams; RAE Retinol Activity Equivalents; RDA Recommended Daily Allowance; SE standard error
  2. Values in this table represent mean ± SE for continuous variables and n (%) for categorical variables
  3. Means were adjusted for variables found to be significantly associated with gender, as per Table 1
  4. *p-values were obtained from comparison of adjusted means using ANCOVA for continuous variables and from chi square for categorical variables
  5. Bolded numbers are significant at p < 0.05
