Figure 2 Threshold Analysis of the Risk of VLST in DES

This graph demonstrates the predicted difference in quality-adjusted life expectancy (QALE) between drug-eluting stents (DES) and bare-metal stents (BMS) over a range of excess risk for very late stent thrombosis (VLST) with DES. At an annual risk of 0.14%/year (over 4 years), the predicted QALE was equal for the 2 strategies, and above this level of risk BMS was the optimal treatment strategy.
