*AAPC, average annual percentage change; APC, annual percentage change in age-standardized mortality rate. Mortality rates expressed as deaths/100,000 population. Values in bold indicate where AAPC or APC differed significantly (p<0.05) from zero (by a 2-sided test for which the true AAPC was zero, calculated based on a t distribution; https://surveillance.cancer.gov/help/joinpoint/setting-parameters/method-and-parameters-tab/average-annual-percent-change-aapc).
