 C-statistics of the TyG index for predicting CV events and MACEs in patients with bifurcation lesions

	C-statistic	ΔC-statistic	P value	NRI	P value	IDI	P value
CV events a
Original model*	0.678 (0.634–0.722)
Original model + TyG index	0.696 (0.651–0.741)	0.018	< 0.001	0.23	0.007	0.81%	0.004
MACEs b
Original model	0.700 (0.650–0.750)
Original model + TyG index	0.713 (0.664–0.763)	0.013	< 0.001	0.25	0.003	0.61%	0.010

^aCV events were defined as a composite of CV death, nonfatal MI, and non-fatal stroke. ^bMACEs were defined as a composite of CV death and nonfatal MI. ^*Original model included age, male sex, BMI, hypertension, diabetes mellitus, ACS presentation, MI histories, TC, LDL-C, hsCRP, serum creatinine, LVEF, and three-vessel disease.
