Baseline risk model including age, BMI, SBP, heart rate, history of stroke, hemoglobin, albumin, HbA1c ALT, eGFR, LVEF, LM/three vessels in angiography findings
ALT: alanine aminotransferase, BMI: body mass index, eGFR: estimated glomerular filtration rate, HbA1c: glycated hemoglobin, IDI, integrated discrimination improvement, SBP: systolic blood pressure, LVEF: left ventricular ejection fraction, LM: left main vessel
