Fig 1 Unadjusted mortality after coronary intervention. (A) Survival according to type of intervention. Dashed lines represent 68% confidence bands equivalent to ± 1 SE. Numbers of patients remaining at risk are below horizontal axis. (B) Instantaneous risk of death. Depiction is as for (A). Note that all interventions are associated with an early rapidly declining phase of risk, a period of constant risk, and a rising phase of risk.

Fig 2 Death among propensity-matched patients after coronary intervention. Format is as for Figure 1A. (A) CABG versus DES patients to 5 years. (B) CABG versus BMS patients to 10 years. (BMS = bare-metal stent; CABG = coronary artery bypass graft surgery; DES = drug-eluting stent.)

Fig 3 Distribution of predicted values for 5-year survival calculated by solving three multivariable equations for each patient receiving coronary artery bypass graft surgery (CABG), percutaneous coronary intervention (PCI) with drug-eluting stent (DES), or PCI with bare-metal stent (BMS).

Fig 4 Screen shot of strategic decision-support tool. Values for variables are recorded on the left, and survival curves are obtained on the right. (CABG = coronary artery bypass graft surgery; EF = ejection fraction; Hx = history; LMT = left main trunk stenosis; MR = mitral regurgitation; y.o. = years old.)
