Table 3 Comparison between the high-risk group and the low-risk group

Risk category	Abnormal cardiac stress test requiring cardiac catheterization and/or CABG		Risk ratio (95%CI)	P value
	Yes, n = 245	No, n = 2083
High risk	236 (96.3%)	1700 (81.61%)	5.31 (2.75, 10.24)	< 0.001
Low risk	9 (3.7%)	383 (18.39%)

CABG: Coronary artery bypass graft; CI: Confidence interval.
