Figure 2. Risk Model Receiver Operating Characteristic Curves to Predict Perioperative Stroke.

Figure 2.

C-statistics, calculated using the sensitivity and specificity of each risk score for the outcome of perioperative stroke, are displayed within the figure. Risk scores between 0.5-0.7 were considered poorly discriminative, between 0.7-0.8 were considered moderately discriminative, and >0.8 were considered highly discriminative.8,9
