Referent category is whites. All hazard ratios are for blacks compared to whites.

Model a: Adjusted for demographic characteristics [age at diagnosis (continuous), sex (male or female), marital status (married, unmarried or unknown), census track median income (log transformed), living in metropolitan city (yes or no)].

Model b: Model a + cancer stage (stage 1 (reference), 2, 3 and 4) and grade (grade 1 (reference), 2, 3 and 4)

Model c: Model b + surgery, chemotherapy, radiation and Charlson comorbidity index (used as a continuous variable with score ranging from 0–13)
