Table 1:

Values of percent relative difference in incidence, $\Delta (a,p\text{-interval})=100\times \sum _{p\text{-interval}}({\lambda }_{a,p}^0-{\lambda }_{a,p,X_0})∕\sum _{p\text{-interval}}{\lambda }_{a,p}^0$. The three intervals are 1980-1994, 1995-2011, and 1980-2011. Results in the table are based on separate models for women aged <50 and ≥50 years.
