Figure 3 (Left) Propensity-adjusted survival derived by proportional hazard Cox regression analysis with race and propensity score (parsimonious model) included as covariates. Dashed line = survival at mean of covariates. (Right) Kaplan-Meier 0- to 12-year coronary artery bypass graft (CABG) survival in matched African-American (AA) (thick lines) versus Caucasian (thin line) patients. Corresponding non-parsimonious model results were essentially identical (see Fig. S2 of the online version of this article).
