Joinpoint Trends - Differences
The trends in reported cancer rates for selected racial groups for specified time periods are summarized by the annual percent changes associated with each line segment obtained from fitting a joinpoint regression model to cancer rates for a time period in question. State Cancer Profiles uses the Joinpoint Regression Program (Version 5.0.1).Recent trends on this site are average annual percent changes (AAPCs) representing the most recent 5 years of data. The entire joinpoint regression line is used to help compute the AAPC. As a result of the differences in the time periods used to fit the models, the AAPCs estimated using the shorter series will be subject to more variability than the ones using the longer series. Although the AAPC from two series estimated using different time periods are not technically comparable, these results can be useful to provide an approximate summary of the trends for practical purposes. To learn more about fitting trends using joinpoint models see http://surveillance.cancer.gov/joinpoint. To learn more about computing AAPCs see https://surveillance.cancer.gov/joinpoint/.
There are two main types of trends on the State Cancer Profiles web site.
Historical Trends, available on the Historical Trends Graph:
Recent Trends, available in numerous places.
Incidence Data
Historical Trends, available on the Historical Trends Graph:- Data available down to the state/registry level
- Unless otherwise stated:
- - Trends start in 2002 for most states (NPCR data source).
- - For SEER areas (Atlanta, Connecticut, Hawaii, Iowa, Los Angeles, New Mexico, Rural Georgia, Seattle, SF-Oak, San Jose-Monterey, Utah)
