A and B Bar graphs comparing the 30-day event rates (death, myocardial infarction, or stroke) among the different AUB-HAS2 score groups in patients ≥ 40 and < 40 years old. In both age groups, there was a gradual increase in the event rates as the AUB-HAS2 score increased with a p value for trend of <0.0001. (C and D) Corresponding Kaplan-Meier curves that further illustrate the powerful discriminatory ability of the AUB-HAS2 index in stratifying peri-operative cardiovascular risk in both age subgroups
