Diagnostic accuracy for ACS of conventional troponin and traditional coronary CTA assessment versus hsTn I and advanced coronary CTA

	Sensitivity (95% CI)	Specificity (95% CI)	PPV (95% CI)	NPV (95% CI)	AUC (95% CI)
Conventional troponin and traditional CTA	100.0% (82.4-100.0)	48.2% (39.7-56.8)	20.7% (12.9-30.4)	100.0% (94.7-100.0)	0.74 (0.70-0.78)
HsTn I and advanced CTA	100.0% (82.4-100.0)	68.1% (59.7-75.7)	29.7% (18.9-42.4)	100.0% (96.2-100.0)	0.84 (0.80-0.88)

PPV – positive predictive value, NPV – negative predictive value, AUC – area under the curve, 95% CI – 95% confidence interval, ACS – acute coronary syndrome, hsTn – highly-sensitive troponin
