^*Adjusted for comorbidities (hypertension, DM uncontrolled, myocardial infarction), use of aspirin, NSAID, multivessel PCI, number of stents, total stent length > 45 mm, minimum of stent diameter < 2.5 mm, ostium lesion, bifurcation lesion, LM lesion.

† Adjusted for comorbidities (hypertension, DM uncontrolled, GI bleeding/ulcer, myocardial infarction), use of aspirin, NSAID, cholesterol, multivessel PCI, number of stents, total stent length > 45 mm, minimum of stent diameter < 2.5 mm, ostium lesion, bifurcation lesion, LM lesion.
