FIGURE 3.
Time-related death after primary isolated coronary artery bypass grafting in diabetics and nondiabetics. Solid lines are parametric estimates enclosed within dashed 68% confidence bands equivalent to ±1 SE. The panels show: (A) instantaneous risk of death (overall); (B) survival (overall); (C) instantaneous risk of death (propensity-matched cohort); and (D) survival (propensity-matched cohort). Each symbol represents a death; vertical bars are confidence limits equivalent to ±1 SE; and values in parentheses are numbers of patients remaining at risk.
