NOTE. Data from the SEER^*Stat Database (“NAACCR Incidence, CINA Analytic File, 1995-2008, for Expanded Races, Standard File”).

Abbreviation: NAACCR, North American Association of Central Cancer Registries.

^*Rates are per 100,000 population and age standardized to the 2000 US population (single ages to 84 years; Census P25-1130).

^†Ovarian cancer (International Classification of Diseases code 56.9); included only malignant carcinomas and excluded noncarcinomas (n = 20,821).

^‡Percent changes were calculated using 1 year for each end point; annual percent changes were calculated using the weighted least squares method.

^§The annual percent change is significantly different from zero (P < .05).

^∥The annual percent changes is significantly different from the annual percent changes for 1995 to 2002 (P < .05).
