Estimates of differences and lower and upper 99 % confidence intervals (CI) at each year post diagnosis are shown. Estimates were obtained while controlling for sex, age at diagnosis, tumor grade, year of diagnosis, and RUCC categories. Two significant (p < 0.001) three-way interactions were included: race/ethnicity by stage by follow-up year, and stage by side by follow-up year. One non-significant (p = 0.076) three-way interaction was also included to enable estimation of these differences of interest: stage by side by race/ethnicity. The model also included all two-way interactions required to build each three-way interaction.
