MACCE is defined as composite of cardiovascular death, non-fatal ST-elevation or non-ST-elevation myocardial infarction, unstable angina, and non-fatal stroke.

Model 1 is adjusted for age, fat mass.

Model 2, adjusted for age, fat mass, smoking (current, former, never), alcohol intake and physical activity.

Model 3, adjusted for age and model 2 variables plus health status (self-reported pharmacologically treated diabetes mellitus, systolic blood pressure, AAC) and medications (vitamin K antagonist, angiotensin-converting enzyme inhibitors, diuretics, fibrates).

Model 4, adjusted for age and model 3 variables plus biological measurements (testosterone, osteoprotegerin, LDL-C, C-reactive protein).
