Figure 1

The left-hand column shows the Fryback and Thornbury model for assessing diagnostic test evidence on the basis of hierarchical levels of clinical outcomes (19). These levels range from technical quality and diagnostic/prognostic accuracy to establishing a test's impact on clinical decision-making to societal outcomes. The findings of both trials are summarized in subsequent columns, providing a comparison of the types of evidence provided by each, as well as the results. CABG = coronary artery bypass graft; ICA = invasive coronary angiography; PCI = percutaneous coronary intervention; Rx = prescription.
