Conditional information

How this model should be used: 
This model can be used to identify patients with pulmonary embolism at risk of an adverse outcome.

Model performance:
Receiver operating characteristic (ROC) curve analysis showed that an appropriate cut-off point for discriminating between the presence and the absence of an adverse event was 4 risk points. Using this category, 166 (81.8%) patients were classified as low risk and 37 (18.2%) as high risk for adverse outcome. The area under the ROC curve (c-index) was 0.84 (95% confidence interval 0.78-0.89, P = 0.0001). Sensitivity and specificity were 68.7% and 91.2%, respectively (figure 1).
