Comparison of Crude and Adjusted Predictive Models of Mortality for African Americans Relative to Caucasians at 1 Year and 3 Years After Diagnosis Among Medicare Beneficiaries (n=201,305) With an Incident Diagnosis of Breast, Lung, Colon/Rectal, or Prostate Cancer as Identified in Surveillance, Epidemiology, and End Results-Medicare Data From 1998–2002
| Mortality: OR (95% CI) | |||
|---|---|---|---|
| Race/Ethnicity | Crude | Adjusted Overalla | Adjusted Cancer-Specific |
| 1-Year mortality | |||
| Caucasian | 1.00 (Referent) | 1.00 (Referent) | 1.00 (Referent) |
| African American | 1.29 (1.24–1.34) | 1.16 (1.10–1.22) | 1.13 (1.07–1.19) |
| 3-Year mortality | |||
| Caucasian | 1.00 (Referent) | 1.00 (Referent) | 1.00 (Referent) |
| African American | 1.38 (1.34–1.43) | 1.22 (1.17–1.28) | 1.23 (1.17–1.30) |
OR indicates odds ratio; CI, confidence interval.
Adjusted models included the covariates age at diagnosis; sex; travel time to the nearest National Cancer Institute cancer center; predominance of primary care before diagnosis; cancer site; rurality; comorbidities; Surveillance, Epidemiology, and End Results registry of residence at diagnosis; median household income of zip code at diagnosis; and year of diagnosis.
