  • Model 1: Crude model of physical activity as a continuous variable (log-MET-min/day). Model 2: model 1 + adjustment for age and gender. Model 3: model 2 + adjustment for history of cardiovascular events. Model 4: model 3 + adjustment for insulin concentration, systolic BP, waist circumference, triglycerides, smoking, and hsCRP. Model 5: model 3 + adjustment for Framingham risk score factors (BP, LDL-cholesterol, HDL-cholesterol, smoking, presence of diabetes). Model 6: model 5 + adjustment for creatinine clearance and urinary protein excretion. Model 7: model 5 + adjustment for 24-hour urinary creatinine excretion. HR, hazard ratio; CI, confidence interval.
