Figure 1 Schematic of the Markov Model
(A) Decision tree representing the outcomes in the first 30 days after the index procedure. (B) Decision tree representing the outcomes in the period 30 days to 6 months. The tree for the period 6 months to 1 year is similar. (C) Bubble diagram shows the initial therapeutic decision between drug-eluting stent (DES) and bare-metal stent (BMS) followed by the first year of life after the index procedure. The Markov health states are represented in the ovals with arrows indicating movement between the states from 1 year to next. Each of the health states were further subdivided on the basis of prior myocardial infarction but is not shown for simplicity and brevity. CABG = coronary artery bypass graft surgery; MI = myocardial infarction; ST = stent thrombosis; TVR = target vessel revascularization.
