Figure 4

Flowchart summarizing the diagnostic workup. For patients in the discovery and validation sets with FLUTHE score system, low possibility group includes 4 patients with AD and 36 patients with non-AD (including 30 with CAD). High possibility group includes 188 patients with AD and 23 patients with non-AD (including 11 with CAD). Medium possibility group includes 70 patients with AD and 84 patients with non-AD (including 50 with CAD). AD: aortic dissection; CAD: coronary artery disease.
