Figure 2 Displays risk-adjusted one year cumulative cost estimates for patients receiving either a coronary stent or PTCA under three clinical scenarios: 1) a 60-year old patient without comorbid illness, 2) the same aged patient with diabetes mellitus, and 3) the same aged patient with multiple comorbid illnesses (diabetes, chronic lung disease, congestive heart failure, history of myocardial infarction and multivessel coronary disease). The solid squares mark the mean for each treatment under each scenario. The diamond and triangles represent the 75th and 25th percentile confidence intervals surrounding this mean estimate.
