Fig. 5. Receiver-operating characteristic curve for γ' fibrinogen in CAD patients.
γ' fibrinogen concentrations were measured in a prior study (7) in 133 patients referred for elective diagnostic cardiac catheterization. The receiver-operating characteristic curve of γ' fibrinogen concentrations in CAD cases and controls showed an area under the curve of 0.76. A maximum diagnostic accuracy of 0.78 was found at a decision threshold of 0.30 g/L.
