Figure 3

Receiver operated characteristic curves for different risk factors at 300 d. Top plots show data from the plaque data set. Bottom plots show data from the PBMC data set. Plots are calculated only from gene expression profiles (left), only from the established risk factors: age, gender, LDL and smoking (middle), or from both gene expression profile and the four established risk factors (left). The straight diagonal line illustrates prediction by pure chance (AUC 0.5), and the curved line describes the prediction possible with the given predictive variables. A theoretical curve along the top left corner would indicate perfect prediction (AUC 1).
