Data are mean (95% CI), treatment difference (95% CI). Total cholesterol, weight, BMI and waist circumference were analysed using mixed models for repeated measurements. Significant covariates included in the models were: *total cholesterol: age, gender and current smoker; †weight: age, gender, height, waist and duration of diabetes; ‡BMI: gender, duration of diabetes and waist; §waist circumference: gender, BMI and non‐smoker.
