Notes:
- Incidence rates are expressed per 1,000,000 population.
- The incidence rate for the state of Idaho is age adjusted to the standard 1970 U.S. population using the direct method.
- The incidence rates for the other geographic areas are the products of the standardized incidence ratios and the state age-adjusted rate.
- Expected cases are based upon age and sex-specific rates for the state of Idaho (compare to observed).
- P-Values compare observed and expected cases, are two tailed, based upon the Poisson probability distribution.
- "<" denotes significantly fewer cases observed than expected, ">" denotes significantly more cases observed than expected (p=.05).
Statistical Note:
- Rates based upon 10 or fewer cases (numerator) should be interpreted with caution.
