Model 1 was unadjusted.

Model 2 was adjusted for age, gender, BMI, race, tobacco use status, and the presence of hypertension, HF, stroke, ARF, CKD, diabetes, cardiogenic shock, as well as revascularization status.

Model 3 included additional adjustments for potassium, chloride, GLU, AG, WBC, RBC, PLT, Hb, RDW, HCT, PT,APTT, BUN, and Cr, based on Model 2.
