Data are n (%), unless otherwise indicated.

*Odds ratios have been estimated by a logistic model, where being at target at 4 years was considered as the dependent variable and belonging to the group of case or control subjects, age, sex, duration of diabetes, familiarity, and situation at baseline were the independent variables.

†McNemar test for paired samples.

‡Friedwald formula: LDL cholesterol = total cholesterol − HDL cholesterol − triglycerides/5 (only patients with triglycerides <4.5 mmol/l included).

§A1C ≤7.0% + systolic blood pressure ≤130 mmHg + diastolic blood pressure ≤80 mmHg + LDL cholesterol ≤2.58 mmol/l (100 mg/dl).
