  1. Continuous data presented as mean (95% CI). Categorical data presented as n (%).
  2. †Means are adjusted for age and sex. *Geometric means (95% CI).
  3. The overall p-value: ethnic differences in continuous and categorical variables were explored by ANOVA and Chi-square tests, respectively. Post hoc pairwise comparisons: ap < 0.05, Aboriginal vs. Chinese, bp < 0.05, Aboriginal vs. European, cp < 0.05, Aboriginal vs. South Asian, dp < 0.05, Chinese vs. European, ep < 0.05, Chinese vs. South Asian, fp < 0.05, European vs. South Asian.
