Cox proportional hazard analyses for the association between RA and TLR and MACE.

	Unadjusted analysis			Adjusted analysis
	Hazard ratio	95% CI	P value	Hazard ratio	95% CI	P value
TLR
MB	(reference)
RA	0.275	0.119–0.635	.003	0.32	0.12–0.853	.023∗
MACE

RA	0.484	0.277–0.859	.013	0.674	0.329–1.381	.282#

CI = confidence intervals, MACE = major adverse cardiovascular events, MB = modified balloon, RA = rotational atherectomy, TLR = target lesion revascularization.

^∗Results are adjusted for age, BMI, LM, No. of predilatation balloons.
