Comparison of statistically optimal and clinically optimal cut-offs with associated sensitivities and specificities on the patient level.

	Statistically optimal cut-offs total study population	Clinically optimal a cut-offs total study population	Clinically optimal a cut-offs with high/very high CVR	Clinically optimal a cut-offs without high/very CVR
Common superficial TA	0.86 mm	1.01 mm	1.03 mm	0.84 mm
Frontal branch of TA	0.68 mm	0.82 mm	0.86 mm	0.71 mm
Parietal branch of TA	0.67 mm	0.69 mm	0.80 mm	0.63 mm
Sensitivity	86.5% (76.9–92.5%)	79.7% (69.2–87.3%)	73.1% (53.9–86.3%)	89.6% (77.8–95.5%)
Specificity	81.4% (70.8–88.8%)	90.0% (80.8–95.1%)	89.3% (72.8–96.3%)	90.5% (77.9–96.2%)

Cut-off values are shown for the compressed lumen technique (combining both walls).

^adefined as sets of cut-offs with approximately 90% specificity on the patient level (from Tables 4, 5). CVR, cardiovascular risk; TA, temporal artery.
