Figure 3. Unadjusted Kaplan–Meier Estimates.
Unadjusted Kaplan–Meier estimates are shown for the rate of the primary composite end point of death from cardiovascular causes, myocardial infarction, or stroke (Panel A) and for the rate of the secondary composite end point of death from any cause, myocardial infarction, stroke, or heart failure (Panel B), according to the change in high-sensitivity cardiac troponin T concentration from baseline to 1-year follow-up. The 4-year event rates are derived from a landmark analysis starting at the time of plasma sample collection at 1 year and continuing to the close of the study 4 years later. I bars indicate 95% confidence intervals. Data on the numbers of events and numbers at risk are for the 1984 patients in the BARI 2D trial who had both baseline and 1-year follow-up troponin T concentrations available.
