AMI, acute myocardial infarction; ASCVD, atherosclerotic cardiovascular disease; IHD, ischemic heart disease; NE, not estimated due to small sample or insignificant results.
Total effect: adjusted for age, smoking, alcohol, exercise, systolic blood pressure (SBP), fasting glucose, and total cholesterol at baseline (’92 and ’94); Direct effect: adjusted for age, smoking, alcohol, exercise, SBP, fasting glucose, and total cholesterol at baseline plus mediators (hypertension, diabetes, and dyslipidemia) (’02 and ’04); % mediated: (TE-DE)/TE * 100.
