Sensitivity-CK-MB	24.11%	86.61%
Specificity-CK-MB	98.21%	66.07%
AUC-CK-MBc	0.614	0.821
95% CId	0.537–0.692	0.786–0.886

^aSensitivity and specificity by CIA were obtained at the cutoffs of 0.04 ng mL⁻¹ for cTnI and 4 ng mL⁻¹ for CK-MB.

^bSensitivity and specificity by pGold chip were obtained at the lowered cutoffs of 0.03 ng mL⁻¹ for cTnI and 3.13 ng mL⁻¹ for CK-MB.

^cAUCs were obtained using the SPSS software (version 19.0, SPSS Inc., Chicago).

^dCI was calculated based on the Clopper–Pearson method.

^ep-Value was calculated based on the two-sided Student’s t-test.
