  1. Estimates representative for the Canadian general population (based on weighted data).
  2. Mean = Geometric Mean.
  3. E Interpret with caution (high sampling variability; coefficient of variation 16.6%-33.3%).
  4. F Estimate not provided because of extreme sampling variability or small sample size.
