Some subjects entered the trial with a BMI or fasting glucose level outside the entry criteria cut-off. This was because they had been identified with either a higher BMI or fasting glucose on recruitment but had made lifestyle changes before the formal baseline examination. In addition BMI and fasting glucose were lower in some control subjects when they entered the study in groups 3 or 4.
