Notes:
* CI denotes confidence interval.

Footnote 1: If values for the standard error and the 95% confidence intervals are not provided, the normal approximation to the binomial distribution does not apply because of the small sample size.

Footnote 2: When the sample size is less than 50, estimates are not precise and should be interpreted with caution.
