§ Sample size is the number of respondents answered lifetime asthma question
If values for the standard error and the 95% confidence interval are not provided, the normal approximation to the binomial distribution does not apply due to small sample size.
When the Sample Size is less than 50, estimates are not precise and should be interpreted with caution.
