Joinpoint Trends - Differences

The trends in reported 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. HDPulse uses the Joinpoint Regression Program (Version 4.9.0.0).

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.
