Data includes: Incidence Rate (95% Confidence Interval) - The incidence rate is based upon 100,000 people and is an annual rate (or average annual rate) based on the time period indicated. Rates are age-adjusted by 5-year age groups to the 2000 U.S. standard million population. Recent Trends - This is an interpretation of the AAPC/APC: Rising when 95% confidence interval of AAPC/APC is above 0. Stable when 95% confidence interval of AAPC/APC includes 0. Falling when 95% confidence interval of AAPC/APC is below 0. AAPC/APC (95% Confidence Interval) - the change in rate over time Average Annual Percent Change - AAPCs are based upon APCs that were calculated by Joinpoint Regression Program Annual Percent Change - APCs calculated in SEER*Stat.
