Figure 2. Decision tree for assessment of screening analysis

The square node represents the decision to screen asymptomatic patients to identify those with low ejection fraction. Each test or combination of tests will result in a true positive, false positive, true negative, or false negative finding. Only those with positive tests are treated to prevent heart failure (e.g., with ACE inhibitors).
