Figure 3: The ROC curve to discriminate TiA cases (n=42) from GD controls (n=927).

Sensitivity, specificity, positive and negative predictive values of the model were 61.09% (95% CI=45.64–76.42), 92.13% (95% CI=90.46–93.60), 21.67% (95% CI=14.67–30.11) and 98.57% (95% CI=97.68–99.18), respectively.
