Model 1, Unadjusted model.
Model 2, Adjusted for age and sex.
Model 3, Adjusted for all covariates: age, sex, PCI, comorbidities such as AMI, CHF, hypertension, diabetes mellitus, CKD, anemia, atrial fibrillation, COPD, and stroke, medicine such as drug hyperuricemia hydrochlorothiazide and furosemide, and laboratory examination such as HDL-CAST, CKMB, and LDL-C.
