  1. Adjusted odds ratios were calculated from a multivariable logistic regression model that included Charlson comorbidity score (modelled as an integer-valued quantitative variable), age at diagnosis (expressed in years), and race (white vs non-white). The unadjusted and adjusted odds ratios, shown here with associated 95% confidence intervals and p-values, are for a single unit increase in comorbidity, a decade increase in age, and the comparison of white vs. non-white for race. Final n for VA adjusted model = 336 (91 metastatic, 245 non-metastatic), final n for FFS adjusted model = 270 (198 metastatic, 72 non-metastatic).
