  2. 1 Cardio-metabolic risk markers included in model 1 are: systolic blood pressure, fasting concentrations of total cholesterol, Apo A-1, insulin, and glucose. Model 2 includes test variables revealing significant effects on cognitive performance after step-wise, one-by-one elimination of non-significant test markers in model 1. 2BP blood pressure.
